(D) The central atom in the nitrate ion $(NO_3^-)$ is nitrogen $(N)$.Nitrogen has $5$ valence electrons.In $NO_3^-$,nitrogen forms one double bond with one oxygen atom and two single bonds with the other two oxygen atoms (one of which carries a negative charge).Thus,the total number of bond pairs around the nitrogen atom is $4$ (one double bond counts as $2$ bond pairs,and two single bonds count as $2$ bond pairs).Since nitrogen has used all $5$ of its valence electrons to form these $4$ bonds (with one electron involved in the coordinate/single bond structure),there are no lone pairs remaining on the nitrogen atom.Therefore,the number of bond pairs is $4$ and the number of lone pairs is $0$.

In the $NO_3^-$ ion,what are the number of bond pairs and lone pairs of electrons on the $N$ atom,respectively?
