QJEEM21Ch9598: JEE Main 2021 Chemistry - Class 12 JEEM21Ch9598 Solution: Diamond has a three dimensional structure of C atoms formed by…
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 ____________.
Step-by-Step Verified Solution
Carbon atoms occupy FCC lattice points as well as half of the tetrahedral voids.
Therefore number of carbon atoms per unit cell = 8
Therefore number of carbon atoms per unit cell = 8
