Can phosphorus with outer electronic configuration 3s^2, 3p^3 form PH_

1.	Can phosphorus with outer electronic configuration 3s^2, 3p^3 form PH_5 ?
Answer» Solution :ALTHOUGH phosphorus exhibits +3 and +5 oxidation STATES, it cannot form `PH_5`. Besides some other considerations, high `Delta_a H` value of dihydrogen and `Delta_(eq)H` value of hydrogen do not FAVOUR to exhibit the highest oxidation state of P, and CONSEQUENTLY the formation of `PH_5`.
