covalent bonding#!#structures

In the diamond form of carbon, there is a network of single, tetrahedrally arragned covalent bonds. The structure of graphite is quite different from that of diamond. Graphitie is composed of many two-dimensional sheets of carbon atoms. The distance between the layers is______pm.

Diamond has a three dimensional structure of C atoms formed by covalent bonds. The structure of diamond has face centred cubic lattice where 50% of the tetrahedral voids are also occupied by carbon atoms. The number of carbon atoms present per unit cell of diamond is_________.

The covalent bond length is the shortest in which of the following bonds
