Chapter 21, Problem 55PS

Interpretation Introduction

Interpretation: To draw the lewis dot structure for sulfide, ${\text{S}}_2{}^{-2}$ ion.

Concept introduction:

The sulfide, ${\text{S}}_2{}^{-2}$ ion is an analogue of peroxide, ${\text{O}}_{\text{2}}{}^{-2}$ ion. Both have similar structures. Sulfur forms anionic chains of $\text{S}$ atom called polysulfides.

Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.

It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
