in phosphuros it can either loose 5 electrons or gain 3 electrons . why can't we do the same in nitrogen?

Expert Answer
The electronic configuration of P is
G.S - 3s2 3px 1 3py1 3pz1 3d0 ............ hence here covalency of P atom is 3(sp3 hybridisation)
E.S. - 3s1 3px 1 3py1 3pz1 3d1 ............here covalency of P atom is 5 (sp3 d hybridisation)
In case of N atom
G.S. - 2s2 2px 1 2py1 2pz1 ...........here covalency is 3 (sp3 hybridisation)
N atom don't have d orbital therefore it not showing variable valency like phosphorous atom.

. Then i have to first react Carbon with Oxygen then react that compond with calcium. So how will i know the valency of compound formed from reaction of carbon with oxygen. We can know the valency of elements from their atomic number and electronic configuration, but how can i know the valency of compound?
Please help,waiting for your reply,
Thank you. Asked by hk.sachdev | 12 Oct, 2018, 10:38: PM
