Valence shell electron pair repulsion (VESPR) theory
A theory that allows prediction of the shapes of molecules based on the idea that electrons- either as lone pairs or as bonding pairs- repel one another
Electron groups
A general term for lone pairs, single bonds, multiple bonds, or lone electrons in a molecule
Linear geometry
The molecular geometry of three atoms with a 180 degree bond angle due to the repulsion of two electron groups
Trigonal planar geometry
The molecular geometry of four atoms with 120 degree bond angles in a plane
Tetrahedral geometry
The molecular geometry of five atoms with 109.5 degree bond angles
Trigonal bipyramidal geometry
The molecular geometry of six atoms with 120 degree bond angles between three equatorial electron groups and 90 degree bond angles between two axial electron groups and the trigonal plane
