Each carbon atom is covalently bonded to four other carbon atoms. A lot of energy is needed to separate the atoms in diamond. This is because covalent bonds are strong, and diamond contains very many covalent bonds. This makes diamond's melting point and boiling point very high.

1.Diamond is a giant covalent structure.The covalent bonds are very strong and require a huge amount of thermal energy to break apart. There are also intermolecular forces that keep the diamondstructure together.
2.Graphite is soft and slippery because there are only weak intermolecular forces between its layers. Graphite is a good conductor of heat and electricity. This is because, like metals, graphite contains delocalised(free) electrons. These electrons are free to move through the structure of the graphite.
