Struture of an atom
This document provides an outline for a presentation on the history and structure of atoms. It begins with the early ideas of Democritus and Thomson, then describes the atomic models of Rutherford, Bohr, and others. The structure of the atom is explained, including the nucleus, protons, neutrons, and electrons. Isotopes and isobars are also introduced. The presentation would provide details on the key scientists and experiments that led to the current understanding of atoms as tiny particles consisting of a nucleus surrounded by electrons.
Atomic number, Mass number, Relative atomic mass and Atomic mass unit
The document discusses atomic number, mass number, and relative atomic mass. It states that the atomic number of an element equals the number of protons in its nucleus. The mass number is the sum of protons and neutrons. An example problem finds an atom has 92 protons and 146 neutrons from a given mass number of 238 and atomic number of 92. Relative atomic mass is the average mass of an atom's isotope compared to carbon-12, measured in atomic mass units.
The Atom
The document defines key atomic terms like atom, nucleus, protons, neutrons, and electrons. It describes how atoms are made up of a tiny nucleus surrounded by an electron cloud. Atoms of the same element have the same number of protons. The number of neutrons and electrons can vary. The periodic table arranges elements in periods and groups based on their atomic structure and number of valence electrons.

Valence Electrons
Valence electrons are the outermost shell electrons of an atom that are involved in bonding. Elements in the same group on the periodic table have the same number of valence electrons because they exhibit similar chemical properties based on their valence electron configuration. Atoms seek to attain a full outer shell of 8 electrons to achieve stability through gaining, losing or sharing valence electrons in chemical bonds.
Atomic structure presentation
Atoms are composed of electrons, protons, and neutrons. Electrons orbit around a small, dense nucleus composed of protons and neutrons. Over time, scientists have developed models of the atom based on new discoveries. Democritus first proposed atoms could not be further divided in 450 BC. In the 19th and 20th centuries, physicists discovered subatomic particles within atoms like electrons, proving atoms could still be divided. Now atoms are understood to have a nucleus surrounded by electron clouds.
Atoms, Molecules, And Matter
An atom is the smallest particle of an element that contains protons, neutrons, and electrons. Elements are substances made of a single type of atom that combine to form molecules, which are made of two or more atoms joined together. Molecules such as water, written as H2O with two hydrogen atoms and one oxygen atom, are the smallest particles that combine without chemical change to form all matter in the world.
Electron,nutron,proton
The document defines and describes several elementary particles and properties of atoms:
- Electrons are negatively charged subatomic particles that have no known components. They have a mass about 1/1836 that of a proton.
- Protons are positively charged subatomic particles found in the nucleus of an atom. The number of protons determines the element and its atomic number.
- Neutrons have no charge and have a mass slightly larger than protons. Along with protons, they make up the nucleus of atoms.
- The atomic number is the number of protons in an atom's nucleus and identifies the element. For neutral atoms, it equals the number of electrons.

Electron configuration
Electron configurations provide information about the location of electrons in an atom's orbitals. There are three main rules for determining electron configurations: 1) electrons fill orbitals starting with the lowest energy levels and moving upwards, 2) the Pauli exclusion principle states that no two electrons can occupy the same orbital with the same spin, and 3) Hund's rule states that electrons will occupy orbitals singly before pairing up. Writing out electron configurations involves determining the element's number of electrons and following the Aufbau principle of filling orbitals in order of increasing energy.
types of chemical bonding
This document discusses three main types of chemical bonding: ionic bonds, covalent bonds, and metallic bonds. Ionic bonds form between metals and nonmetals through the transfer of electrons from one atom to another, producing charged ions. Covalent bonds form between nonmetals of similar electronegativity through the sharing of electron pairs. Metallic bonds form between metallic elements through a shared "electron cloud" that holds the atoms together strongly.
Electronegativity
Linus Pauling introduced the concept of electronegativity in 1932 to help explain the nature of chemical bonds. Electronegativity is a property that reflects an atom's ability to attract electrons in a bond. Atoms with high electronegativity strongly attract electrons, while atoms with low electronegativity attract electrons weakly. Whether a bond is ionic or covalent depends on the difference in electronegativity between the bonded atoms - a large difference leads to ionic bonds where one atom takes the electrons, while a small difference leads to covalent bonds where electrons are shared. Electronegativity values help predict bond type based on this principle.

The Structure of an Atom
Atoms are the basic building blocks of all matter and are made up of a nucleus containing protons and neutrons surrounded by electrons. John Dalton's atomic theory established that atoms are indivisible and that different elements are composed of different types of atoms. Rutherford discovered that the nucleus contains a concentrated positive charge and most of an atom's volume is empty space. Niels Bohr's model represented electrons orbiting the nucleus in fixed energy levels like planets around the sun, explaining atoms' distinct properties and how they form bonds.
Valence Electron
The document summarizes key information about atomic structure:
- The nucleus is positively charged and contains nearly all an atom's mass, while electrons are much smaller and negatively charged, orbiting in shells outside the nucleus.
- Electrons are arranged in shells (also called energy levels) around the nucleus, with the first shell holding up to 2 electrons and subsequent shells holding up to 8 electrons each.
- Atoms can be represented using Bohr models that show the nucleus and electrons arranged in shells, with the number of protons and neutrons indicated in the nucleus.
Unit 9 Chemical Bonding
The document discusses chemical bonding and Lewis structures. It explains that valence electrons are involved in bonding and can be represented using electron dot diagrams called Lewis structures. Lewis structures show the arrangement of electrons around elements using dots to represent valence electrons. The octet rule states that atoms seek to acquire a noble gas configuration by gaining, losing or sharing electrons to obtain eight electrons in their outer shell. There are two main types of bonds: ionic bonds formed by electron transfer between atoms and covalent bonds formed by electron sharing between atoms.

Chapter 2 the structure of the atom
The document discusses the structure of atoms and isotopes. It begins by defining matter and the particle theory of matter. It then explains that atoms are made up of protons, neutrons and electrons. The atomic structure of various elements is discussed through their electron configurations. Isotopes are then introduced as atoms of the same element that have the same number of protons but different numbers of neutrons. Examples of isotopes including hydrogen and oxygen isotopes are provided.
Ions cations and anions
Ions are atoms that have gained or lost electrons, giving them an electrical charge. Atoms that lose electrons become positively charged cations, while atoms that gain electrons become negatively charged anions. The number of protons and neutrons remain the same in an ion, only the number of electrons changes. Ionic bonding occurs through the transfer of electrons from one atom to another, while covalent bonding involves the sharing of electron pairs between two atoms. Sodium chloride is an example of ionic bonding through electron transfer, while an oxygen molecule is held together by covalent bonding from shared electron pairs.
Structure Of Atoms
The document discusses the structure of atoms. Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells.

Atoms are composed of a nucleus containing protons and neutrons surrounded by an electron cloud. The nucleus contains positively charged protons and neutral neutrons. Negatively charged electrons reside outside the nucleus in the electron cloud. The number of protons defines the identity of an element and is equal to its atomic number. The total number of protons and neutrons is the mass number. The number of electrons equals the number of protons to maintain electroneutrality. Models such as the Bohr model depict electron arrangement in shells surrounding the nucleus.

ions and its types class 9th
This document defines ions as positively or negatively charged atoms or groups of atoms. It describes two types of ions - cations, which are positively charged and formed when an atom loses electrons, and anions, which are negatively charged and formed when an atom gains electrons. Examples of common cations include sodium (Na+) and magnesium (Mg2+), while examples of common anions include chloride (Cl-) and oxide (O2-). The document explains that ions are formed through gains or losses of electrons, resulting in an unequal number of protons and electrons that creates a positive or negative charge.
Atoms And Subatomic Particles
An atom is incredibly small, with its diameter needing to be increased 200 million times to equal the diameter of a penny. Atoms are made up of subatomic particles, including protons and neutrons in the central nucleus and electrons orbiting the nucleus. Most of an atom's mass comes from its nucleus. The number of protons determines the element and is called the atomic number. Isotopes are atoms of the same element that differ in their number of neutrons.

The attractive force which holds various constituents (atom, ions, etc.) together and stabilizes them by the overall loss of energy is known as chemical bonding. Therefore, it can be understood that chemical compounds are reliant on the strength of the chemical bonds between its constituents; The stronger the bonding between the constituents, the more stable the resulting compound would be.
What are atoms?
Atoms are the basic building blocks of all matter and consist of a small, dense nucleus surrounded by electrons. The nucleus contains protons and neutrons, with protons providing a positive charge and neutrons having no charge. Electrons orbit the nucleus and have a negative charge, keeping the overall atom electrically neutral. Atoms can vary in the number of neutrons while maintaining the same number of protons, creating different isotopes of an element. Radioactivity occurs when unstable atoms undergo nuclear decay and emit particles or energy.

Texas v. Johnson (1989)
Gregory Johnson burned an American flag during a political protest and was convicted under Texas law of desecrating a flag. The Supreme Court ruled that flag burning is a form of symbolic speech protected by the First Amendment. While some found the flag burning offensive, causing offense is not enough to prohibit speech. The Court determined that Johnson's actions were a protected form of expression and symbolic speech under the freedom of speech clause of the First Amendment.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Made up of a dense, positively charged nucleus surrounded by a system of electrons. neutron nucle us proton -electron -proton -neutron Atoms usually do not divide in chemical reactions except for some removal, transfer, or exchange of specific electrons.
- 4. What are Atoms composed of? Atoms have 4 major parts to it: -Nucleus -Neutron -Proton -Electron
- 5. Proton Stable positivelycharged nuclear particle. A stable elementary particle that is a component of all atomic nuclei Carries a positive charge equal to that of the electron's negative charge.
- 6. Electron A stable negatively charged elementary particle Has a small mass that is a fundamental constituent of matter and orbits the nucleus of an atom Electrons in a circle by a magnetic field
- 7. Neutron Elementary particle without any electric charge (neutral charge). A zero electrical charge and a mass approximately equal to that of a proton
- 8. Nucleus The positively charged central region of an atom. Consists of protons and neutrons and containing most of the mass.
