What is the hybridization of phosphorus in each of the molecules or ions?

PCl3 - sp3

PBr5 - sp3d

P4O6 - sp3

PO4^3 - sp3

P4 - sp3

Explanation:

Hybridization refers to the combination of atomic orbitals to yield hybrid orbitals of equal energy.

Hybridization occurs between atomic orbitals that are relatively close to each other in energy. The number of atomic orbitals involved in the hybridization is the same as the total number of hybrid orbitals formed.

Whenever phosphorus is bonded to three other atoms, the phosphorus atom is sp3 hybridized. The lone pair on phosphorus atom occupies one of the hybrid orbitals. When phosphorus is bonded to five atoms, the hybridization of the phosphorus atom is sp3d. All valence electrons are utilized in bond formation.
