Question

In $N{O}_3^{-}$ ion, the number of bond pair and lone pair of electrons on nitrogen atom is/are :

• A. 2,2
• B. 3,1
• C. 1,3
• D. 4,0

Answer 1

Answer: (D)

4,0

In $N{O}_3^{-}$ ion, the number of bond pairs (4 Bonds attached to nitrogen) and lone pairs of electron on nitrogen are 4 and 0 respectively.

This we can determine from its lewis dot structure.

Hence option D is correct.
