Chapter 9, Problem 9.7P

Interpretation Introduction

Interpretation:

The Lewis structure and resonance structures of ${\text{NO}}_{\text{2}}^{-}$ are to be written.

Concept introduction: Lewis structure represents the bonds present between the atoms in a molecule and the valence electrons surrounding the atom in the molecule.

A formal charge is the charge assigned to an atom in a molecule. It is assumed that electrons in all bonds are shared equally between atoms regardless of relative electronegativity.
