VSEPR Theory
Valence Shell Electron Pair Repulsion (VSEPR) theory predicts molecular geometry based on the principle that electron pairs around a central atom repel each other and arrange themselves to minimize repulsion. Lone pairs occupy more space than bonding pairs, which affects bond angles. The electron geometry describes the arrangement of all electron pairs, while molecular shape describes only the arrangement of atoms.
