Q. The number of atoms per unit cell of bcc structure is:

The Solid State

Solution:

In bcc structure,

The number of atoms at corners per unit cell $=\frac{1}{8} \times 8=1$

The number of atoms at body centre per unit cell $=1$ atoms

$\therefore $ Total number of atoms per unit cell $=1+1=2$ atoms
