Two chemistry and engineering students from Colorado State University-Pueblo attended the 15th annual Mars Society Convention in Pasadena, California and witnessed the August 6th landing of the Curiosity rover on Mars. Later that day, the students presented on how to produce oxygen and fuel from Martian resources using a Sabatier reactor and solar-powered electrolysis. Over 200 scientists and NASA engineers attended the convention, which coincided with the Mars Science Landing project. The students gained valuable experience presenting their research to professionals and experts in the field of space exploration.
Atoms & the Periodic Table Review
The document discusses elements and the periodic table, including the properties of protons, neutrons, and electrons; atomic structure; atomic number; valence electrons; periodic trends; electron configurations; and groups on the periodic table. It asks questions about the location of mass in an atom, gold's atomic number and protons/electrons, bromine's protons, why scientists don't create a periodic table of compounds, hydrogen and lithium's valence electrons, which group elements belong to, how electrons fill energy levels, electron dot diagrams for vanadium, periods and rows on the periodic table, and what element is represented by an atom cookie. It also reviews distinguishing chemical and physical properties/changes, conservation of mass, and experimental variables.
Physical Science 5.1 : Arranging the Elements
Dmitri Mendeleev arranged the elements in order of increasing atomic mass in 1869 and discovered repeating patterns in their properties. This became known as the periodic table. Mendeleev predicted properties of elements not yet discovered that would fill gaps in the table. Later, Henry Moseley arranged elements by atomic number in 1914, which better fit the periodic patterns. The periodic table classifies elements as metals, nonmetals, and metalloids based on their location and number of outer electrons. Periods are horizontal rows that show repeating patterns, and groups are vertical columns of elements with similar properties.

This document provides information about key chemistry concepts including:
- Chemistry is the study of connections between the everyday world and molecular world, explaining properties and behaviors of matter.
- Atoms are the smallest component of an element, having its chemical properties. Elements are pure substances made of one type of atom.
- The nucleus contains protons and neutrons at the center of an atom. Protons have a positive charge, neutrons have no charge, and electrons orbit around the nucleus and have a negative charge.
- The periodic table organizes elements by atomic number and similar properties, with periods representing electron shells and groups representing outer electrons.

Death by Tylenol
In 1982, two firefighters from a
Chicago suburb were casually
discussing four bizarre deaths that had recently
taken place in a neighboring area. As they
discussed the circumstances of the deaths, they
realized that each of the victims had taken
Tylenol. Their suspicions were immediately
reported to police investigators. Tragically,
before the general public could be alerted,
three more victims died after taking poison-
laced Tylenol capsules. Seven individuals,
all in the Chicago area, were the first
victims to die from what has become
known as product tampering. A forensic
chemical analysis of Tylenol capsules
recovered from the victims’ residences
showed that the capsules were filled
with potassium cyanide in a quantity
ten thousand times what was
needed to kill an average person.
It was quickly determined that the
cyanide was not introduced into the bottles
at the factory. Instead, the perpetrator methodically
emptied each of twenty to thirty capsules and then refilled them with
potassium cyanide. The tampered capsules were rebottled, carefully repackaged,
and placed on the shelves of six different stores. The case of the Tylenol murders remains
unsolved, and the $100,000 reward offered by Tylenol’s manufacturer remains unclaimed.

The document provides information about the periodic table and its history. It describes how Hennig Brand discovered phosphorus in 1649. Julius Lothar Meyer developed one of the first periodic tables in 1862 organizing elements into families based on valence. Dmitri Mendeleev created the first recognizable modern periodic table in 1869, arranging elements by atomic mass and predicting new elements. Henry Moseley observed that atomic number varied periodically, establishing it as the basis of classification in 1914. The rest of the document defines periodic table terms and provides facts about common elements.
The periodic table of elements
The periodic table is an arrangement of the chemical elements based on their properties. Elements are organized by atomic number and similar properties repeat periodically. The periodic table has evolved over time as scientists like Dobereiner, Newlands, Mendeleev, and Moseley discovered patterns in elements and used these patterns to organize the elements. The modern periodic table is a visual representation of the periodic law, which states that properties of elements are periodic functions of their atomic numbers. It provides information about each element's atomic number, atomic mass, electron configuration, and chemical properties.

CHAPTER 4 : THE PERIODIC TABLE OF ELEMENTS
(THE DEVELOPMENT OF PERIODIC TABLE)
CH2.pdf
This document provides an overview of the early history and development of atomic theory in chemistry. It discusses how early Greek philosophers proposed ideas about atoms and the four classical elements. It then describes how alchemy dominated for 2000 years, during which time elements were discovered and mineral acids prepared. The foundations of modern chemistry were established in the 16th-17th centuries through quantitative experiments by Robert Boyle and Antoine Lavoisier's verification of the law of conservation of mass through careful weighing experiments. Lavoisier also discovered that combustion involved oxygen, not phlogiston as previously believed. After 1800, chemistry advanced through quantitative experiments determining chemical compositions and Proust's law of definite proportions.

The document discusses the historical development of atomic theory from ancient Greek philosophers to modern scientists like John Dalton. It describes key contributions such as Robert Boyle's concept of corpuscles, Lavoisier's definition of elements and discoveries about oxygen and water, and John Dalton's chemical atomic theory. Dalton's theory merged the concepts of atoms and elements and was based on empirical evidence supporting laws like the law of conservation of mass and the law of definite proportions. Later scientists like Gay-Lussac, Avogadro, and Mendeleev further expanded atomic theory.

Mendeleev created the first successful periodic table in 1869 by arranging elements by atomic mass and leaving gaps for undiscovered elements. The modern periodic table is arranged by atomic number based on the repeating properties of elements, and classifies elements into blocks and groups with similar properties. The periodic table provides an organized framework for studying and predicting the properties of all known elements.
Ch1103
The document discusses the development of the periodic table. It describes early attempts by scientists like Dobereiner, de Chancourtois, and Newlands to classify and organize the known chemical elements. It then focuses on the key contributions of Dmitri Mendeleev and Lothar Meyer, who independently proposed the periodic law stating that properties of elements are periodic functions of their atomic weights. Mendeleev is credited with publishing the first recognizable version of the modern periodic table in 1869, arranging elements by property groups and leaving gaps for undiscovered elements, some of which he accurately predicted properties for like gallium and germanium. His work established the periodic table as essential for classifying and understanding the elements.
Chemistry , it's History , Concepts , Types
Chemistry is the branch of science concerned with the substances that matter is composed of, their properties, and how they interact or combine. The document provides a brief history of chemistry, outlining key figures and discoveries from ancient civilizations through the 20th century that advanced the field. It describes the main branches of chemistry - organic, analytical, physical, inorganic, and biochemistry - and provides short definitions of each.
Physical Science.M2-SYNTHESIS.pptx
This document discusses the history and discovery of the atomic theory and elements. It describes early Greek philosophers' ideas of atoms as indivisible particles, and how the concept developed over time. Landmark discoveries and experiments are mentioned, such as Thomson's discovery of electrons, Rutherford's nuclear model of the atom, and Chadwick's discovery of neutrons. Methods of synthesizing new elements like particle acceleration and nuclear reactions are also summarized.
History Of Periodic Table
This document summarizes the history of the periodic table, beginning with Aristotle's theory of four elements in 330 BC. It then discusses key contributors such as Lavoisier, Berzelius, Dobereiner, Newlands, Meyer, and Mendeleev who developed early classifications and periodic tables of the elements in the 17th-19th centuries. The modern periodic table took shape in the early 20th century with discoveries like the noble gases, determination of atomic numbers, and transuranium elements. Many scientists collectively contributed to developing the systematic arrangement of elements now known as the periodic table.
Periodic table work
The document summarizes key aspects of the periodic table, including its history, development, structure, and organization. It discusses the discovery of elements and early classification attempts by scientists like Döbereiner and Newlands. It then describes Mendeleev's development of the periodic table and its completion with noble gases. The summary defines the modern periodic table's groups and periods based on electron configuration. It also briefly discusses the blocks and provides definitions of acids and bases.
Periodic table
1. The document discusses the discovery and classification of chemical elements over time. It describes how early scientists like Aristotle and Lavoisier attempted to classify elements based on their properties.
2. In the 19th century, scientists including Dalton, Proust, Dobereiner, Newlands, and Meyer proposed various theories and periodic tables to classify and arrange elements.
3. In 1869, Dmitri Mendeleev published the first recognizable modern periodic table, arranging elements by atomic mass and leaving gaps for undiscovered elements, which was a major breakthrough in chemistry.
Periodic table
Dmitri Mendeleev created the periodic table by organizing the known elements based on their atomic masses and properties into periods and groups. He saw a pattern that allowed him to predict properties of undiscovered elements. The periodic table arranges elements into families including non-metals, alkali metals, alkaline metals, transition metals, metalloids, other metals, halogens, noble gases, lanthanides and actinides.
Periodic table
Dmitri Mendeleev created the periodic table in 1869 as an organized way to show the known elements arranged by atomic number and their chemical and physical properties. The periodic table organizes elements into rows and columns called periods and groups based on their valence electrons and similar atomic orbitals within the same period. Examples provided are hydrogen which can power cars, oxygen which is necessary for breathing, and helium which is used to inflate balloons.
Chemistry Essay
Lithium is a soft, silvery metal that is the lightest of all metals and the first element in the alkali metal family, having an atomic number of 3. As the least dense of all metals, lithium has a low melting point of 180 degrees Celsius and is very reactive, especially with water. Lithium and its compounds have various industrial and medical uses such as in lithium-ion batteries, psychiatric medications, and air treatment to remove carbon dioxide from the air.
Historical background on the development in chemistry iii
Democritus first proposed the existence of atoms in 460 BC, though the atomic theory was not widely accepted until John Dalton proposed it in 1803 based on the laws of multiple and constant proportions. The discovery of subatomic particles like the electron by J.J. Thomson in 1897 and proton by Rutherford in 1911 led to proposed atomic models like the plum pudding model and nuclear atom. Defining the mass and charge of these particles along with isotopes observed by Francis Aston and the neutron discovered by James Chadwick in 1932 completed the basic components of the modern atomic theory.
