Silicon carbide (SiC) is a

Options

A. Ionic solid
B. Molecular solid
C. Covalent solid
D. Metallic solid

Answer

To determine the type of bonding in silicon carbide (SiC), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Elements**: Silicon carbide is composed of silicon (Si) and carbon (C).

2. **Understand the Structure**: Silicon and carbon both have the ability to form covalent bonds. Silicon has four valence electrons, and carbon also has four valence electrons.

3. **Determine the Bonding Type**: In silicon carbide, silicon and carbon atoms share electrons to achieve a stable electronic configuration. This sharing of electrons indicates that the bond formed between silicon and carbon is a covalent bond.

4. **Analyze the Arrangement**: The silicon and carbon atoms in SiC are arranged in a tetrahedral structure. Each silicon atom is covalently bonded to four carbon atoms, and each carbon atom is covalently bonded to four silicon atoms, creating a three-dimensional network.

5. **Conclude the Type of Solid**: Since silicon carbide consists of a network of covalent bonds throughout the structure, it is classified as a covalent solid.

### Final Answer:
Silicon carbide (SiC) is a covalent solid.
