(a)

Interpretation Introduction

Interpretation:

The Lewis structure of ${\text{Ba}}^{\text{2+}}$ ion has to be given.

Concept Introduction:

Lewis structure:

  The representation of valence shell electrons around the atom is known as Lewis structure or Lewis dot structure.  Electrons are represented as a dot in Lewis structures, a single dot represents unpaired electron and paired of dots represents paired electrons.
