1)  Construction/Atomic Arrangement –

Diamond is made up of carbon atoms. Carbon is tetravalent.

∴ Each carbon atom forms 4 covalent bonds.

Diamond cubic structure is combination of two interpenetrating FCC sub-lattices along the body diagonal by ¼th  cube edge. One sub-lattice has its origin at (0,0,0) & other sub-lattices …
