JEE Previous Year 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 ___
Topic: JEE PYQ
Answer: 8. Full step-by-step solution below.
Correct answer: 8
Solution
(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
