What is the hybridization state for the central phosphorus atom in a phosphate ion?   Terms. In a molecule of phosphorus pentachloride, PCl 5, there are five P–Cl bonds (thus five pairs of valence electrons around the phosphorus atom) directed toward the corners of a trigonal bipyramid. Within the framework of hybridization, one may look at the bonds in the phosphate anion as having a great deal of ionic character. However, the whole concept can be better explained if you understand Drago’s Rule. I understand that the hybridization in the phosphate ion is s p 3 since phosphorous forms 4 sigma bonds with 4 of the oxygens and there are no lone pairs on the phosphorous atom.
