(a)

Interpretation Introduction

Interpretation:

The type of crystalline solid that $\text{SiC}$ forms is to be determined.

Concept introduction:

The solids can be classified into 5 types on the basis of the type of particle used in the crystal as follows:

1. Atomic solids

2. Molecular solids

3. Ionic solids

4. Metallic solids

5. Network covalent solids

In atomic solids, the atoms interact through the dispersion forces while in molecular solids the molecules interact through intermolecular forces. In ionic solids, the ions are held together by ionic interactions. In metallic solids, the atoms are bonded through metallic bonding while in the network covalent solids the atoms are bonded by the covalent bonds.
