In diamond, each carbon atom forms four sigma bonds to 4 other carbon atoms in a tetrahedral arrangement with all bond angles 109.5°.Diamond is extremely hard, has a high melting and boiling temperature because of the strong covalent C-C bonds.
Diamond is a giant structure of carbon atoms covalently bonded to four other carbon atoms. The bonds spread through the structure so it is a giant structure.
Each carbon atom has four electrons in its outer shell so can form four single covalent bonds with other carbon atoms.The four electron pairs repel each other according to the electron pair repulsion theory. In three dimensions the bonds are tetrahedral with a bond angle of 109.5°.Diamond is very hard, has a very high melting point of 3700K and does not conduct electricity because there are no free charged particles to carry charge.
