Predicting the Shapes of Molecules . There is no direct relationship between the formula of a compound and the shape of its molecules. The shapes of these molecules can be predicted from their Lewis structures, however, with a model developed about 30 years ago, known as the valence-shell electron-pair repulsion (VSEPR) theory.. The VSEPR theory assumes that each atom in a molecule will ...
