The valency of nitrogen in NH₃ is-

Correct option is C

The correct answer is (c) 3.
· In NH₃ (ammonia), nitrogen has a valency of 3. This means that nitrogen forms three covalent bonds with three hydrogen atoms to complete its octet.
Information Booster:
· Valency: Valency is the combining power of an element, usually determined by the number of electrons in the outermost shell that can be lost, gained, or shared in forming chemical bonds.
· Nitrogen: Nitrogen has five electrons in its outer shell (electron configuration: 2, 5). To achieve a stable configuration (octet), it needs three more electrons, which it obtains by sharing three electrons with three hydrogen atoms, forming three covalent bonds.
· Ammonia (NH₃): In ammonia, nitrogen shares its three unpaired electrons with three hydrogen atoms, resulting in a stable molecule with nitrogen at the center.
