It can be ionised though, and then it prefers to take up 3 electrons and thereby become phosphide with a -3 charge. The Lewis structure with the lowest formal charges on the atoms is almost always the most stable one. Other depictions, which reject a large degree of d-orbital utilization in hybridization, might give a negative formal charge to all the oxygens and a positive formal charge to the central phosphorus by eschewing the $\ce{P=O}$ double bond. The formal charges of the atoms... For dinitrogen monoxide, the arrangement of the atoms is N-N-O. If you were to have a single bond from each oxygen, then for one of the bonds, phosphorus would have to undergo a co-ordinate covalent bond, donating 2 electrons to oxygen.
