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 ____________.
Answer (integer)
8
Solution
Carbon atoms occupy FCC lattice points as well as half of the tetrahedral voids. <br><br>Therefore number of carbon atoms per unit cell = 8
