Chapter 12, Problem 8SAQ

Interpretation Introduction

Interpretation:

Type of solid in dry ice (solid carbon dioxide) is to be determined.

Concept introduction:

Type of solid is determined by the type of interactions present in the solid.

There are 4 types of crystalline solids:

1. Ionic solids: Made up of positive and negative ions held together by electrostatic attractions.
2. Molecular solids: Made up of molecules or atoms. Force between them is London dispersion forces, hydrogen bond or dipole-dipole forces.
3. Metallic solids: Made up of metal atoms. Force of attraction is metallic bonds between them.
4. Covalent network: Made up of atoms held together by covalent bonds. Also called as atomic solids.
