Valence Shell Electron Pair Repulsion (VSEPR) model. ... is based on the number of regions of high electron density around a central atom. ... can be used to predict structures of molecules or ions that contain only non-metals by minimizing the electrostatic repulsion between the regions of high electron density.

Valence shell electron pair repulsion – extraordinary though this may sound – is not based on any deep theory. It is simply a 'neat trick' that works extraordinarily well.

Valence Shell Electron Pair Repulsion (VSEPR) theory allows the Chemist to predict the 3-dimensional shape of molecules from knowledge of their Lewis Dot structure. In VSEPR theory, the position of bound atoms (ligands) and electron pairs are described relative to a central atom.
