Hybridization Involving d Orbitals Atoms in the third period and higher can utilize d orbitals to form hybrid orbitals PF 5 Similarly hybridizing one s , three p and two d orbitals yields six identical hybrid sp 3 d 2 orbitals. These would be oriented in an octahedral geometry . Hybrid orbitals allows us to use valence bond theory to describe covalent bonds (sharing of electrons in overlapping orbitals of two atoms) When we know the molecular geometry, we can use the concept of hybridization to describe the electronic orbitals used by the central atom in bonding Steps in predicting the hybrid orbitals used by an atom in bonding:
