Question

give reason nitrogen does not show five covalency like phosphorus

Answer 1

Answer:

it is because size of nitrogen is small w.r.t. phophorous

and has not d orbital in electronic shell

so it does not show 5 covalency like phosphorous

hope it hlps to u

Answer 2

Nitrogen doesn't show 5 covelancy because it has 5 electrons in its outermost shell and it need only three more electron to get the configuration of its nearest nobel gas and it can't expand it's orbit like other elements because they have vacant d orbital while nitrogen doesn't have.

hope it helps.......
