Each carbon atom is covalently bonded to four other carbon atoms in diamond. A lot of energy is needed to separate the atoms. This is because covalent bonds are strong. This is the reason why diamond has a high melting point.
All the carbon atoms of Diamond are said to possess strong chemical bonds with that of the four other carbon atoms, thus making a perfect tetrahedron structure and on throughout the crystal. The carbon atoms, here are sp3 hybridized, and the bond lengths of the carbon-carbon atom are equal. Hence, Diamond forms a three-dimensional network of strong covalent bonds.
- Diamond is known to be the hardest substances on the Earth. It is used in making of tools that are utilized for grinding, cutting, drilling, etc.
- It is used in the making of jewellery.
