This document discusses the molecular structure of atoms. It begins by explaining that all substances are composed of elements, which are the basic substances, and that elements are made up of very small particles called atoms. It then describes the basic structure of an atom, including that atoms have a small, positively charged nucleus surrounded by negatively charged electrons. The number of protons determines the element and equals the number of electrons. Atoms can gain, lose, or share electrons to attain stable electron configurations, forming ions or molecules.
C02 Atomic Structure.ppt
This document outlines key concepts about atomic structure including:
1) The structure of atoms including protons, neutrons, and electrons that make up the nucleus and electron cloud.
2) Atomic properties such as atomic number, mass number, and relative atomic mass.
3) Electron configuration, isotopes, ions, and molecules of elements and compounds.
4) Learning objectives are to describe atomic structure, state particle properties, define related terms, list uses of isotopes, and predict bonding based on structure.
Atomos, Teorías Atómicas, Teoría Cuántica, Masa Atómica e Isotopos
The document provides information about atoms and their subatomic particles. It defines the atom as the smallest particle of an element that retains its characteristics. It describes atoms as consisting of protons, neutrons, and electrons. The number of protons defines the element and its atomic number, while the total of protons and neutrons is the mass number. Isotopes are atoms of the same element with different numbers of neutrons. Electron configuration diagrams show how electrons are arranged in an atom's energy levels.
Orbital Notation
The document discusses orbital notation, which visually represents electron configuration by showing the placement and spin of each electron in an atom. It defines key terms like Pauli exclusion principle, Aufbau principle, and Hund's rule that govern how electrons fill atomic orbitals. Examples are given of writing the electron configurations of sodium, boron, titanium, and calcium using orbital notation with half arrows to symbolize individual electrons.
Electron Configuration
The document discusses electron configuration and the rules for filling electron orbitals in atoms. It explains that electrons exist in energy levels called shells, with each shell able to hold a maximum number of electrons according to the formula 2n2, where n is the shell number. Within shells, electrons occupy specific atomic orbitals that have distinct shapes and are grouped into sublevels. The document outlines Hund's rule and the Aufbau principle for determining the order in which orbitals are filled with electrons. Several examples of deducing full electron configurations for different elements are also provided.
Econfig Pres
The document discusses electron configuration and the rules that govern how electrons fill atomic orbitals:
1) The Pauli Exclusion Principle states that each orbital can hold two electrons with opposite spins.
2) The Aufbau Principle states that electrons fill the lowest energy orbitals first, following the "lazy tenant rule."
3) Hund's Rule states that within a sublevel, one electron will occupy each orbital before pairing electrons, following the "empty bus seat rule."

The document discusses electron configurations and the Pauli Exclusion Principle. It explains that electrons are described by four quantum numbers and that the Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers. Orbital energies are determined by factors like orbital size and shielding effects. Electron configurations are written according to the Aufbau principle and Hund's rule, filling lower energy orbitals first with parallel spins when possible.

How to draw methane ch4 lewis structure
The document provides instructions for drawing the Lewis structure of methane (CH4). It explains that you first determine the number of valence electrons for each atom, which is usually the same as the group number on the periodic table. For methane, carbon contributes 4 electrons and each hydrogen contributes 1. These are summed to get the total of 8 valence electrons. Bonds are then drawn between the atoms to give each atom an octet of electrons, following the octet rule. The completed Lewis structure for methane shows each carbon bonded to 4 hydrogens and each hydrogen bonded to the carbon.
How to draw the lewis structure of carbon monoxide
The document provides instructions for drawing the Lewis structure of carbon monoxide (CO). It explains that carbon contributes 4 valence electrons and oxygen contributes 6, for a total of 10. A carbon-oxygen single bond is drawn by pairing 2 electrons between them. However, carbon then only has 6 electrons and needs 8 to complete its octet. Therefore, oxygen must donate its remaining 2 electrons to carbon to form a triple bond, completing the octet for both atoms.
How to write the lewis structure of carbon disulfide
The document provides steps to write the Lewis structure for carbon disulfide (CS2):
1. Determine the number of valence electrons for each atom (C has 4, S has 6). Total valence electrons for CS2 is 10.
2. Draw an initial sketch showing the atoms. Place each atom's valence electrons around it.
3. Form single bonds between atoms by pairing their valence electrons. Additional electrons are needed to complete the octet of each sulfur atom.
4. The final Lewis structure shows each carbon and sulfur atom with 8 electrons, completing their octets.

Electron configuration worksheet
- 1. Electron configuration worksheet Using the electron configuration chart given at: http://periodictablewithnames.net/electronconfigurationchartandworksheet/ solve the following exercises. I. Write a ground state electron configuration for each neutral atom listed below. Ground state means that all of the lowest possible energy levels (up to the proper number of electrons for the element) are filled. 1. K 2. Pb 3. Sc 4. Ra 5. O 6. Ag 7. Ru 8. Ce 9. I 10. F 2. Write a ground state electron configuration for these ions. Ions can gain or lose electrons so remember that a positive ion (cation) has less number of electrons than its neutral form whereas a negative ion (anion) has more electrons than its neutral form. Example: C4+ is a cation thus has 4 electrons less than its neutral form C0. If C0 has 6 electrons and its configuration is 1s2 2s2 2p2, then C4+ should have only two electrons; thus its electron configuration would be 1s2. 11. O2- 12. Fe3+
- 2. 13. Br-1 14. Ni2+ 15. K+ 16. Cu2+ 17. F-1 18. Ca+2 3. Choose 3 possible elements or ions that may represent the following electron configurations 19. 1s2 2s2 2p6 3s2 3p6 4s2 3d1 20. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 21. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 22. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 23. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d4 24.
