Question

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 ________.

MARKS Content Team · Accepted Answer

Correct answer: 8. Carbon atoms occupy FCC lattice points as well as half of the tetrahedral voids therefore number of carbon atoms atoms per unit cell =8

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 ________.
