Answer
Nitrogen
Reason — To attain the stable electronic configuration of the nearest noble gas neon, nitrogen needs three electrons.
When two nitrogen atoms come closer, each contributes three electrons and so they have three shared pair of electrons between them. Both atom attain an octet, resulting in the formation of a triple covalent bond [N≡N] between them.
