Chapter 12, Problem 80E

Interpretation Introduction

Interpretation: Each of the given solids is to be identified as molecular, ionic, or atomic.

Concept introduction: Solids may be crystalline or amorphous. Crystalline solids are of three types:

Molecular Solids are made up of molecules as the composite units. For example: ${\text{H}}_{\text{2}}{\text{O, SO}}_2,\text{etc}.$

Ionic Solids are made up of units of cations and anions. For example: $\text{NaCl, KCl, etc}\text{.}$

Atomic Solids are made up of individual atoms as the composite units. They may be metallic solids $\left(\text{K, Na, Li, }\text{}\text{Al, etc}\text{.}\right)$, covalent solids like diamond $\left(\text{C}\left(s\right)\right),$ or nonbonding solids like xenon, krypton, and helium.
