Percentage of free space in a body-centred cubic unit cell is

A

0.34

B

0.28

C

0.3

D

0.32

Text Solution

Verified by Experts

The correct Answer is:
D
The ratio of volumes occupied by atoms in unit cell to the total volume of the unit cell is called as packing fraction or density of packing. For body-centred cubic structure, packing fraction = 0.68 i.e., 68% of the unit cell is occupied by atoms and 32% is empty.
