Octet Rule
Octet Rule
Atoms tend to gain, lose, or share electrons to achieve a full outer electron shell (8 electrons), similar to a noble gas configuration.
Valence Electron
Valence Electron
Electrons in the outermost energy level of an atom, actively involved in chemical bonding.
Covalent Bond
Covalent Bond
A chemical bond formed when atoms share one or more pairs of electrons to achieve a full outer shell.

Study Notes
General Chemistry 1 - Quiz 2
- Chemical Bonding Stability: Dictated by Electronic Configuration
- Valence Electron: Electrons in the outermost energy level, not atomic number, first, or second energy levels.
- Octet Rule: Describes the stability of elements during chemical bonds. Many elements' stability is achieved by having eight valence electrons.
- Lewis structures: Helps predict the bonding and arrangement.
- Electrons surrounding an Oxygen atom (OF2): 2 lone pairs of electrons
- Violates Octet Rule Element: AsF5
- Completely Filled Valence Electron Atoms: Radium
- Nitrogen's Octet Completion: Needs 3 electrons to gain an octet.
- Octet Rule Completion for Reactants: Atoms react with each other to attain 8 electrons in their outermost energy level.
- Octet Rule Formulator: Gilbert N. Lewis
- Covalent Bonding: A type of chemical bonding where atoms share electrons to achieve stability.
- Polar molecules: Have unequal sharing of electrons where the shared electrons are not equally shared.
- Nonpolar molecules: Equal sharing of electrons where the shared electrons are equally shared.
- Lone pairs/unshared pairs: Unshared electrons are on an atom in a molecule.
- Number of covalent bonds (Carbon): 4
- Shape (Methane): Tetrahedral
- Shapes with 2 electron pairs: Linear & Angular
- Shape with 2 electron pairs and 2 lone pairs (bond angle 109.5°): Trigonal Pyramidal
- Octahedral Shape (bond angle): 90°
- Trigonal Planar (bond angle): 120°
- Molecular Structure of Water (H₂O): Bent shape, 104.5° bond angle.
- Molecular shape with a bond angle of 120° (choose from 27 choices): Not possible for determination from the given text.
- Drawing AB3E molecules: Use Lewis Electron Dot Diagram
