Interpretation Introduction

Interpretation:

Among amorphous, ionic, molecular, covalent, network or metallic solids, the type of silicon carbide solid should be determined.

Concept introduction:

The main classes of crystalline solids can be characterized as follows:

(1) Ionic solids: These types of solids can be formed by particles known as ions that kept together through strong ionic forces. An example of ionic solid is $\text{NaCl}$. The $\text{NaCl}$ crystal is formed by ${\text{Na}}^{+}$ and ${\text{Cl}}^{-}$ ions.

(2) Molecular solids: These solids are formed by particles called molecules. These molecules are kept together through weak hydrogen bonding and also Van der Waals forces. The example of this type of solid is sucrose.

(3) Covalent network solids: In these solids, atoms are kept together through covalent bonding and quartz.is an example of covalent network solid.

(4) Metallic solids: These types of solid are arrangement of large number of atoms and they also show metallic properties such as electrical conductivity. The example of this solid is iron and silver.
