Diamond has a three dimensional structure of CC atoms formed by covalent bonds. The structure of diamond has face centred cubic lattice where 5050 % of the tetrahedral voids are also occupied by carbon atoms. The number of carbon atoms present per unit cell of diamond is ________.

Correct answer

0

Step-by-step solution

Carbon atoms occupy FCC lattice points as well as half of the tetrahedral voids

therefore number of carbon atoms atoms per unit cell =8= 8
