Question

calculate the number of atoms in different cubic unit cell ​

Answer 1

Explanation:

Number of body diagonals in a cube = 4

Therefore, number of atoms on the body diagonals = 2 x 4 = 8

These atoms lie within the unit cell and are not shared.

Contribution from the atoms at the corner = 8 x 1/8 =1

Therefore, total number of atoms in the cubic unit cell = 8 + 1 = 9
