Skill 7.7 Using VSEPR theory to explain molecular geometry and polarity 

Electron pairs Geometrical arrangement Predicted bond angles Example 

X represents a generic central atom. Lone pair electrons on F are not shown in the example molecules. 

The shape of a molecule is given by the location of its atoms. These are connected to central atoms by shared electrons, but unshared electrons also have an important impact on molecular shape. Unshared electrons may determine the angles between atoms. Molecular shapes in the following table take into account total and unshared electron pairs. 

Electro n pairs All shared pairs 1 unshared pair 2 unshared pairs 3 unshared pairs 4 unshared pairs
