The periodic table
The periodic table arranges elements from left to right based on increasing atomic number. Elements in the same column or group have similar properties, while properties gradually change across each period or row from left to right as atoms get smaller but more massive. The periodic table was created by Russian chemist Dmitri Mendeleev and represents each element with a chemical symbol and atomic number to classify its identity and properties.
Chapter #2 Lecture Part 2
Atomic and molecular masses can be measured precisely using mass spectrometry, while average atomic masses used in calculations account for isotope abundances. The periodic table organizes elements and shows repeating patterns of their chemical properties and reactivities. Chemical formulas indicate the number and type of atoms in compounds, and different formula types provide varying levels of structural information. Ions are formed when atoms gain or lose electrons to become positively-charged cations or negatively-charged anions, and ionic compounds consist of ionic bonds between oppositely-charged ions.
The periodic table
The periodic table arranges elements in order of increasing atomic number and groups elements with similar chemical and physical properties. Elements are organized into rows called periods and columns called groups. The periodic table can be used to determine the number of protons, electrons, and neutrons in an atom based on its atomic number and mass number. Elements in the same group have the same number of electrons in their outer shell, which is equal to the group number for groups 1 to 7. Noble gases make up group 0 and are unreactive because their outer shell is full.
The Periodic Table Presentation 1
The document provides an overview of the development of the periodic table. It discusses early chemists like Lavoisier who compiled lists of known elements. In the 1860s, Newlands and Meyer began to notice patterns in properties of elements when arranged by atomic mass. Mendeleev later created the first periodic table by arranging elements in order of atomic mass with similar properties grouped together. This table had some issues resolved by Moseley in 1913, who arranged elements by atomic number, establishing the modern periodic table and periodic law.
Basic concepts of modern periodic table
The document provides an overview of the periodic table including its development, characteristics, and positioning of elements. It discusses:
- There are 118 known elements placed in the periodic table based on their electronic configurations. Metals lie on the left side and non-metals on the right, separated by metalloids.
- The horizontal rows are called periods and there are 7 periods. Elements in the same period have consecutive atomic numbers. The vertical columns are called groups and elements in the same group have similar properties despite having different atomic numbers.
- Noble gases are placed on the far right. Early periodic tables were arranged by atomic mass but Mendeleev organized his 1871 table based on properties, allowing prediction of unknown
Periodic Law
The document summarizes the history and development of the periodic table. It describes how early chemists like Cannizzaro, Mendeleev, and Moseley contributed to organizing the elements based on their atomic masses and properties. The modern periodic table is arranged by increasing atomic number and groups elements with similar properties together in periods and families. Key periodic properties like atomic radius, ionization energy, and electronegativity are influenced by an element's position on the table.
The periodic table
The periodic table is a chart that arranges the chemical elements by atomic number and displays their properties. It is divided into 18 groups and 7 periods, with elements classified as metals, nonmetals, alkali metals, alkaline earth metals, halogens, and noble gases. The periodic table helps identify elements, solve problems involving elements, and determine atomic mass and valence. Groups show trends in properties down the column, while periods show more significance horizontally in some regions.

- In 1866, John Newlands proposed an early periodic table called the Law of Octaves, which arranged elements in order of increasing atomic mass and observed that elements with similar properties recurred every eighth element. However, it had many limitations in its application.
- In 1869, Dmitri Mendeleev created the first successful periodic table. It arranged elements in order of increasing atomic mass but also grouped elements with similar properties together. Mendeleev left gaps for undiscovered elements and was able to accurately predict their properties.
- The modern periodic table is based on atomic number rather than atomic mass. It overcomes limitations of earlier tables and groups elements with the same number of protons, electrons, and chemical properties together

Elements within the same group have similar properties due to their valence electrons. The periodic table is useful for organizing information about elements and predicting chemical behaviors.
Chapter 4- periodic classification of elements
Elements were first classified into metals and non-metals based on their properties. Later, Mendeleev classified elements into periods and groups in his periodic table based on their atomic masses and properties of oxides and hydrides. Mendeleev's periodic table had vacant spaces that allowed for the prediction and discovery of new elements. However, some elements were not in strict atomic mass order and the positions of hydrogen and isotopes remained unclear.

Periodic table
Dmitri Mendeleev created the periodic table in 1869 by arranging known elements in order of atomic weight and grouping them into columns and rows based on their chemical and physical properties. Elements are arranged with metals on the left, non-metals on the right, and metalloids in between. Elements in the same vertical group have similar properties due to their shared number of valence electrons. Elements are also arranged horizontally in periods based on the number of electron shells in their atoms. The periodic table organizes elements based on atomic structure and recurring trends in physical and chemical properties.
Periodic table
The document discusses the periodic table. It defines the periodic table as the tabular arrangement of chemical elements based on their atomic numbers, with vertical columns called groups and horizontal rows called periods. Properties of elements are periodic functions of their atomic numbers. The modern periodic table is based on the periodic law proposed by Henry Moseley. While scientists proposed various early forms, Dmitri Mendeleev developed the renowned 1869 periodic table that was systematically devised with empty cells for missing elements. The modern periodic table contains 118 total elements, with 94 naturally occurring on Earth and the rest synthetic.
The Periodic Table Of Elements
Dmitri Mendeleev is considered the father of the periodic table. In 1869, he created one of the first recognizable periodic tables that arranged elements based on increasing atomic mass. It included 17 columns with gaps for elements not yet discovered. Later, in 1871, he revised his table to include 8 columns and more accurately predicted properties of undiscovered elements. Today's periodic table arranges elements by atomic number instead of mass and includes all known elements. It categorizes them into metals, nonmetals, and metalloids based on their physical and chemical properties.

ATOMIC-STRUCTURE.pdf
Atoms are made up of three fundamental subatomic particles: protons, neutrons, and electrons. The atomic number of an element determines its identity and represents the number of protons in its nucleus. Isotopes are atoms of the same element that have different numbers of neutrons, giving them different mass numbers but the same chemical properties. Electrons orbit the nucleus in shells at increasing distances from the nucleus. The number of electrons in the outer shell determines an element's chemical properties and reactivity.

Periodic table
This document provides an overview of key chemistry concepts related to the periodic table. It defines matter as anything that occupies space and has mass. Elements are described as pure substances that cannot be broken down further, while atoms are the basic units of elements composed of protons, neutrons, and electrons. The periodic table organizes elements by atomic number and mass. Isotopes are variants of the same element with different numbers of neutrons. Electrons occupy energy levels around the nucleus and the number in the outermost level determines an element's properties and ability to react. Covalent and ionic bonds involve the sharing or transfer of electrons between atoms.

This document discusses atomic, nuclear and particle physics concepts including:
- Atomic energy levels and line spectra which provide evidence that electrons can only have certain discrete energy values within an atom.
- The Bohr model of the atom which assumed quantized electron energy levels and explained hydrogen atom spectra.
- Nuclear structure including mass number, nucleons, atomic number, isotopes, and interactions within the nucleus.
- Three types of nuclear radiation - alpha, beta, and gamma rays - and how they differ in their ionizing properties and penetration abilities due to their mass and charge.
- Nuclear stability and how heavier nuclei require more neutrons to counter the repulsive force between protons.

Basic chem1 atomic structure
1. Biology relies on chemistry as living things are made up of matter composed of atoms and molecules. 2. Chemical reactions within and between these molecules drive biological processes in organisms. 3. Understanding the chemical structure and reactions of matter is therefore essential for biologists to study life processes at the cellular and molecular levels.
Atoms, elements and the periodic table
This document discusses atoms, elements, and the periodic table. It contains the following key points:
1. Atoms are composed of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit the nucleus. The number of protons determines the element.
2. Elements are arranged in the periodic table in order of increasing atomic number. Elements in the same vertical column have similar properties.
3. The periodic table allows scientists to predict properties and discover "missing" elements based on patterns in electronic structure and atomic structure.
HUDA 9TH PPT-1.pptx
This document defines key concepts about atomic structure, including:
1) Atoms are the building blocks of matter and consist of smaller subatomic particles like protons, neutrons, and electrons.
2) The nucleus is at the center of the atom and contains protons and neutrons. Electrons orbit the nucleus in energy levels.
3) Protons are positively charged, neutrons have no charge, and electrons are negatively charged. The number of protons determines the element.
Atoms
This document provides an overview of atomic structure and properties. It discusses John Dalton's atomic theory, early atomic models including Thomson's plum pudding model and Rutherford's nuclear model. Later, it describes Bohr's model of electron orbits and different atomic orbitals. The document also defines key atomic properties including atomic number, mass number, and isotopes.
Atomicsstructure
- Atoms are the building blocks of matter and are made up of protons, neutrons, and electrons. The nucleus contains protons and neutrons and accounts for nearly all an atom's mass, while electrons orbit the nucleus.
- The number of protons determines the element and cannot be changed. Neutrons can vary between atoms of the same element, creating isotopes of that element.
- An atom's mass number is the total number of protons and neutrons, while its atomic mass refers to the average mass of all isotopes of that element as found in nature.
BE UNIT-1 basic electronics unit one.pptx
1. The document discusses the atomic structure of matter, which is made up of protons, electrons, and neutrons. Atoms contain protons and neutrons in their nucleus, surrounded by electrons.
2. Atoms of different elements have different atomic structures because they contain different numbers of protons and electrons. Neutral atoms have equal numbers of protons and electrons, but atoms can gain or lose electrons to become ions.
3. The document then discusses subatomic particles like protons, neutrons, and electrons in more detail, including their relative masses and charges. It also discusses isotopes and how they have the same number of protons but different numbers of neutrons.
Atomic Theory
The document discusses atomic theory and the structure of atoms. It explains that all matter is made up of atoms, which are the smallest particles of elements that can exist. Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons determines the element, while the number of neutrons can vary between isotopes of the same element. Chemical bonds form when atoms share or transfer electrons to fill their valence shells. This allows the formation of compounds with properties different from their constituent elements.

The document discusses key concepts about atoms including:
1) Atoms are made up of protons, neutrons, and electrons with protons being positively charged and electrons being negatively charged.
2) The periodic table organizes elements based on their number of protons (atomic number) and mass number.
3) Chemical equations show reactants yielding products while conserving mass according to the law of conservation of mass.
Are you rotating or revolving
The document discusses the difference between rotation and revolution as it relates to Earth and other celestial bodies. It explains that rotation is turning on an axis, like a figure skater or basketball, while revolution is moving around another object in an orbit, like a tetherball around a pole or Earth around the Sun. The document aims to teach students about how Earth's rotation causes day and night and its revolution causes changes in seasons, as outlined in several Texas Essential Knowledge and Skills science standards.
Galaxies nebulae stars notes
Within galaxies, star forming regions called nebulae contain clouds of dust, hydrogen and helium gases. Stars sometimes form within these nebulae as the gases and dust collapse under their own gravity. A nebula with protostars, or young stars that are still forming, is shown in the diagram. The document then goes on to describe the life cycle of stars like our Sun and the changes it will undergo as it evolves and eventually dies in approximately 5 billion years.
Classification of stars notes w questions
In the early 20th century, astronomers Henry Russell and Ejnar Hertzsprung constructed a diagram called the Hertzsprung-Russell diagram (HR diagram) that compares the luminosity and surface temperature of stars. The HR diagram serves as an important tool for astronomers to classify stars and reveal relationships between stars by showing them at different ages and stages of evolution. It classifies stars into groups based on their surface temperatures from hottest, blue-white group O stars to coolest, red group M stars.
How astro gather info space
Astronomers gather information about space by detecting and analyzing electromagnetic radiation emitted or transmitted from celestial objects. Different types of electromagnetic radiation, including radio waves, visible light, and others, provide data about distances, properties, compositions and motions when collected by telescopes and studied. Spectroscopy techniques separate light into spectra that reveal characteristics of astronomical sources like temperature, density, and chemical makeup through unique spectral patterns.
Topography let s_take_a_hike_ (1)
A topographic map uses contour lines to show elevation and terrain features. The document explains what contour lines are and how they represent points of equal elevation. It then uses examples of hiking up and down a hill to demonstrate how to read elevations on a topographic map using contour lines. Finally, it provides a topographic map example and questions to test the reader's understanding of reading elevations from the contour lines.
Topo and satellite views notes
Topographic maps and satellite views are used to interpret landforms and predict how erosion may change them over time. Cartographers create topographic maps using data from aerial photos and satellites, which photograph the Earth's surface. Topographic maps model the three-dimensional landscape using contour lines that connect points of equal elevation, with closer lines indicating steeper slopes. Contour lines never cross and show the shape and elevation of an area.
Plate tectonics notes
Plate tectonics describes how the Earth's crust is divided into tectonic plates that move relative to each other. The movement of plates is caused by convection currents in the asthenosphere and results in major geological events at plate boundaries like earthquakes, volcanoes, and mountain building. There are three types of plate boundaries - divergent where plates move apart, transform where they slide past each other, and convergent where they push together.
Warm up week of december 15
The document discusses Alfred Wegener's theory of continental drift and plate tectonics. It provides multiple choice questions about Wegener's idea being called continental drift. Additional questions cover the differences between continental drift and plate tectonics, matching plate boundaries with their associated geological features, and identifying the type of plate boundary associated with features like volcanoes, trenches that destroy crust, and faults.
Physical vs chemical changes notes
Physical changes alter a substance's appearance or structure but do not change its chemical composition. Examples include melting, freezing, and dissolving. Chemical changes form new substances with different chemical compositions through rearrangement of atoms, as evidenced by production of a gas, change in temperature, formation of a precipitate, or color change. Common chemical changes are rusting, tarnishing, burning, cooking, and digesting.

Physical changes alter a substance's appearance or structure but do not change its chemical composition. Examples include melting, freezing, and dissolving. Chemical changes form new substances with different properties through rearrangement of atoms, as seen in rusting, burning, and cooking. Evidence of a chemical change may include production of a gas, change in temperature, formation of a precipitate, or color change. A chemical change can be confirmed if the products of a chemical equation are different from the reactants.
Balancing chemical equations notes
This document discusses balancing chemical equations. It explains that a chemical equation uses symbols and formulas to represent a chemical reaction and must obey the law of conservation of mass. This law states that the number and type of atoms on the reactants side must equal the number and type on the products side. The document shows an example of an unbalanced equation and uses coefficients to balance the atoms, resulting in an equation that follows the law of conservation of mass.
Atom notesshort
The document discusses the structure of atoms. It explains that atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons determines the element's identity and the number of neutrons plus protons determines the atom's mass number. Electrons occupy different energy levels surrounding the nucleus. The number of valence electrons in the outermost shell determines an element's chemical properties and reactivity.

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Speaker: Diego Blas (IFAE/ICREA)
Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
