In diamond 4 carbon atoms are strongly bonded with covalent bond and they form giant covalent structure which requires large amount of energy to break down, that’s why diamond has a high melting point. It does not conduct electricity.

Answer:

Each carbon atom is covalently bonded to 4 other carbon atoms in diamond. A large amount of energy is required to split these atoms apart. This is because of the fact that covalent bonds are strong.
