Valence Bond Method y Bonds are formed by overlapping orbitals from each atom in a molecule. y Mixing of s, p and d orbitals on each atom creates special hybrid orbitals for bonding. y The atoms reorganize their orbitals in order to minimize the energy of bonding and proper orientation for bonding. y Two electrons can be in each hybrid orbital during bonding.
