Nitrogen forms a simple diatomic molecul...

Nitrogen forms a simple diatomic molecule but other elements of same group do not form. Explain.

Text Solution

Verified by Experts

Atomic size of nitrogen is very less. Hence 'N' atom can approach close to another 'N' atom. This facilitates the lateral overlap of the p-orbitals forming `pi-` bonds.
Due to large size, other atoms of the same group form only single bonds, but not multiple bonds.
