Chapter 11, Problem 16PE

(a)

Interpretation Introduction

Interpretation:

In the formation of ionic compound ${\text{K}}_{\text{2}}\text{S}$, the electron transfer has to be shown by using Lewis structures.

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.

(b)

Interpretation Introduction

Interpretation:

In the formation of ionic compound ${\text{Ca}}_{\text{3}}{\text{N}}_{\text{2}}$, the electron transfer has to be shown by using Lewis structures.
