Chapter 10, Problem 10.85QE

Interpretation Introduction

Interpretation:

The ground state electronic configuration, the bond order, and the stability of ${\text{He}}_{\text{2}}{}^{\text{2+}}$ ion have to be given.

Concept Introduction:

The bond order is the number of electrons pairs shared between two atoms in the formation of the bond.

Bond order $\text{=}\frac{\left({\text{N}}_{\text{b}}\right)\text{-}\left({\text{N}}_{\text{a}}\right)}{\text{2}}$

Where, ${\text{N}}_{\text{b}}$ is number of electrons in bonding orbital.

${\text{N}}_{\text{a}}$ is number of electrons in antibonding orbital.
