Chapter 12, Problem 12.61E

Interpretation Introduction

Interpretation:

The electron configurations for ${\text{O}}_2{}^{2+}$, ${\text{O}}_2{}^{-}$, and ${\text{O}}_2{}^{2-}$ are to be determined by using Figure 12.23.

Concept introduction:

Electronic configuration tells about the arrangement of the electrons in each subshell of an atom. The distribution of the electrons in the molecules is described by the molecular orbital theory.
