Question

below is a lewis structure for the nitrate polyatomic ion.
:o: | o=n—o: ^-1
how many sigma bonds does this ion have? hint: only type a numeric number/digit, no words/text
how many pi bonds does this ion have? hint: only type a numeric number/digit, no words/text

Explanation:

Step1: Identify sigma bonds

In a Lewis structure, single bonds are sigma bonds, and each double bond has one sigma and one pi bond. The nitrate ion (\(NO_3^-\)) has one double bond (N=O) and two single bonds (N-O). So sigma bonds: 1 (from double bond) + 2 (from single bonds) = 3.

Step2: Identify pi bonds

A double bond has one pi bond, and single bonds have no pi bonds. The nitrate ion has one double bond, so pi bonds = 1.

Answer:

(for sigma bonds):
