Chapter 12, Problem 12.51QP

(a)

Interpretation Introduction

Interpretation:

The given compound is whether ionic, metallic, molecular solid or covalent solid has to be identified.

${\text{CO}}_2$

Concept Introduction:

Ionic solids constitute of ions of opposite charges.  Molecular solids are formed by covalent molecules which are either polar or non-polar.  Covalent solids are formed by atoms of same non-metallic elements and non-polar molecules.  The atoms that are capable of forming repeated chain-like bonding form covalent solids. The repetitive bonding results in three dimensional macro structures.  Metallic solids are composed of metal atoms in which they exist as positively charged ions amidst of pool of electrons.  The pool of electrons are nothing but the electrons lost by the metal atoms and they are delocalized in the entire crystal lattice.
