Why is the melting point of diamond high, in spite of the fact that it is covalent in nature?

Explanation

### Step-by-Step Solution:

1. **Understanding Diamond's Structure**:
- Diamond is an allotrope of carbon, meaning it is one of the different forms that carbon can take.
- In diamond, each carbon atom is sp³ hybridized, forming a tetrahedral shape. This means that each carbon atom is bonded to four other carbon atoms.

2. **Visualizing the Bonding**:
- The structure can be visualized as a three-dimensional network where each carbon atom is bonded to four other carbon atoms. This creates a very strong and stable framework.
