Vedclass · Answer

(A) The central atom in ammonia $(NH_3)$ is nitrogen $(N)$.Nitrogen has $5$ valence electrons.In $NH_3$,nitrogen forms $3$ covalent bonds with $3$ hydrogen atoms,which accounts for $3$ bonding pairs of electrons.After forming these $3$ bonds,$2$ electrons remain on the nitrogen atom,which constitute $1$ lone pair of electrons.Therefore,the structure of ammonia contains $3$ bonding pairs and $1$ lone pair.

How many bonding and lone pairs of electrons are present in the structure of ammonia $(NH_3)$?
