Chemistry Lecture Notes - GSG Review

These flashcards cover key vocabulary and concepts from the lecture notes on Lewis Structures, formal charge, resonance, and molecular geometry.

Lewis Structures

Visual representations of how electrons are shared and arranged around bonded atoms.

Formal Charge

A bookkeeping method used to keep track of charge location in molecules, calculated using the formula: FC = VE – LP – 0.5*BE.

Resonance

The phenomenon where a molecule can be represented by multiple valid Lewis structures that differ only in the arrangement of electrons.

Electron Domain Geometry (EDG)

A model that describes the three-dimensional arrangement of electron domains around a central atom.

Steric Number

The total number of electron domains (bonding and lone pairs) surrounding a central atom, which helps to determine its molecular geometry.

Octet Rule Exceptions

Situations in which atoms do not follow the octet rule, including atoms with odd electrons, those with less than an octet, and those that can have more than an octet.

Bonded Pairs

Pairs of electrons that are shared between two atoms in a bond, represented by a line in Lewis structures.

Lone Pairs

Pairs of valence electrons that are not involved in bonding, represented by dots in Lewis structures.

Electron Domain

Regions in space with high electron density around a central atom, significant for determining molecular geometry.

Molecular Geometry

The spatial arrangement of atoms in a molecule, determined by the position of bonding pairs and lone pairs around the central atom.
