Chapter 12, Problem 5ST

Interpretation Introduction

Interpretation:

The electron dot formula for carbonate ion, ${\text{CO}}_{\text{3}}{}^{2-}$ is to be drawn. The option that corresponds to the number of nonbonding electron pairs in a carbonate ion, ${\text{CO}}_{\text{3}}{}^{2-}$ is to be stated.

Concept introduction:

The Lewis structures are also called electron dot structures. In the Lewis structure, electrons are denoted by dots. These dots represent the number of electrons present in the outer most shell of an element. The electron pairs shared by the atoms are termed as bonding electrons. Other electrons which do not participate in bond formation but complete the octet around each atom are termed as nonbonding electrons or lone pairs.
