How many number of atoms are there in a cube based unit cell, having one atom on each corner and 2 atoms on each body diagonal of cube?

A
6
B
4
Correct answer
C
9
D
8

Solution

Total atoms in a cube based unit cell $$ =\left[\frac{8}{8}+2 \times 4\right]=1+8=9 $$

Hence, the correct answer is option: 'C'.
