State true or false
Diamond is a non conductor of electricity.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement given is "Diamond is a non-conductor of electricity." We need to determine whether this statement is true or false.

2. **Properties of Diamond**: Diamond is a form of carbon where each carbon atom is tetrahedrally bonded to four other carbon atoms. This structure is a three-dimensional arrangement.

3. **Hybridization**: In diamond, the carbon atoms undergo sp³ hybridization. This means that each carbon atom forms four sigma bonds with four neighboring carbon atoms.

4. **Presence of Free Electrons**: For a substance to conduct electricity, it must have free-moving electrons. In diamond, all the valence electrons of carbon are involved in bonding with other carbon atoms, leaving no free electrons available to conduct electricity.

5. **Conclusion**: Since diamond does not have any free electrons, it cannot conduct electricity. Therefore, the statement "Diamond is a non-conductor of electricity" is true.

**Final Answer**: True
