Chapter 10, Problem 10.90QE

Interpretation Introduction

Interpretation:

The electronic configuration of ${\text{Li}}_{\text{2}}{}^{\text{+}}\text{and}{\text{Li}}_{\text{2}}{}^{\text{-}}$ ions has to be given and their bond orders have to be compared with the bond order of ${\text{Li}}_{\text{2}}$ molecule.

Concept Introduction:

Bond order is calculated as,

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.
