Question

what is the valency of carbon and nitrogen

Answer 1

valency of carbon is 4 nd nitrogen is 3

Answer 2

Heya !!!!

---- Here is your answer ---

See ----->

Carbon atomic no is 6
So electronic configuration is 2 , 4


Since valency is no of electrons on outermost shell so valency is 4


No for nitrogen

Atomic number - 7

So electronic configuration is 2 ,5

And since valency is the no of electron in outermost shell

But valency cannot be more than 4


So ( 8 - 5) = 3
