Question

Why valency of nitrogen is 3 instead of both 3 & 5 as in the case of Phosphorus

Answer 1

Explanation:

Both nitrogen and phosphorus have 5 valence electrons, but nitrogen has valency of 3 while phosphorus has valency of 3 or 5. Why is this so?

Maybe phosphorus can gain 3 electrons or remove 5 electrons.But is it possible to remove 5 electrons? Or is it that phosphorus valence shell is farther away than nitrogen, so it is easier for phosphorus to also remove 5 electrons but nitrogen cannot
