Answer

(d) Nitrogen

Reason

The valency of nitrogen element is 3. Nitrogen needs three electrons to attain stable octet structure of nearest noble gas – Ne [2,8].

Each of the two N atoms contributes three electron so as to have three shared pair of electrons between them. Both atoms attain stable – octet structure, resulting in the – formation of a – triple covalent bond [N≡N] between them
