The VSEPR Theory

The VSEPR (Valence Shell Electron Pair Repulsion) Theory is a simple technique used for predicting the shape or geometry of simple covalent molecules. It assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.

The following video clip enumerates the different types of molecular structures. Blue represents the central atom, white represents the atoms bonded to the central atom, and red represents lone electron pairs (pairs of nonbonded electrons in the central atom.)
