WebVSEPR theory is built on two key principles: Electron pairs repel each other. Because of this, they try to position themselves as far apart from each other as possible, giving molecules with the same number of electron pairs the same basic shape. Lone pairs of electrons repel other electrons more than bonded pairs. WebCHM151LL: VSEPR and Molecular Geometry Tables Valence-Shell Electron-Pair Repulsion (VSEPR) model Lewis structures show the two-dimensional distribution of atoms and electrons.
