Why is diamond a bad conductor of electricity but a good conductor of heat?

Explanation

To understand why diamond is a bad conductor of electricity but a good conductor of heat, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Electrical Conductivity**:
- Electrical conductivity in materials is primarily due to the presence of free electrons. Free electrons are those that are not bound to any specific atom and can move freely throughout the material, allowing electric current to flow.

**Hint**: Remember that electrical conductivity relies on the movement of free electrons.
