Maximum covalency of nitrogen is ______________.
(i) 3
(ii) 5
(iii) 4
(iv) 6


NCERT Class XII

Chapter 7. The p-block elements

Answer 1

Nitrogen differs from the rest of the members in group 15 due to its small size, high ionization enthalpy and non availability of d orbitals.
************************************************
Covalency is the number of shared paired of electrons between its atom.

So the maximum Covalency of nitrogen is Four - 4
Example : DiNitrogen pentaoxide- N2O5
************************************************

Answer 2

The maximum Co valency of nitrogen is Four - 4.
Nitrogen is little bit different from the other group 15 elements  due to its small size and absence of d orbitals.
