Phosphorus cannot form PH5 with its outer electronic configuration as 3s23p3 because.

Can phosphorus with outer electronic configuration 3s2 3p3?

Can phosphorus with outer electronic configureation 3s^2 3p^3 " form "PH_5? 5 oxidation state of phosphorus is not possible.

Can phosphorus with outer electronic configuration 3s23p3 form PH5 explain?

Comment. Although phosphorus exhibits +3 and +5 oxidation states, yet it can not form PH₅. Because of high ∆_H–H and slightly negative ∆ e.g. H (electron gain enthalpy), dihydrogen acts only as a weak oxidising agent. ... Hence P forms PH₃ and not PH₅.
