The molecular geometry, or three-dimensional shape of a molecule or polyatomic ion, can be determined using valence-shell electron-pair repulsion (abbreviated VSEPR and pronounced “VES-per”) theory, in which the basic principle is valence electrons around a central atom stay as far apart as possible to minimize the repulsions.

Molecular Geometry. For each molecule, draw the Lewis structure first, then apply the VSEPR model according to the following rules: 1. Count the number of electron pairs around the central atom (both bonding pairs and unshared pairs). Treat double and triple bonds as if they were single bonds. 2. Refer to the table given below to predict.
