Question

The number of atoms per unit cell of bcc structure is: (A) 1 (B) 2 (C) 4 (D) 6

Tardigrade Admin · Accepted Answer

In bcc structure, The number of atoms at corners per unit cell =(1/8) × 8=1 The number of atoms at body centre per unit cell =1 atoms ∴ Total number of atoms per unit cell =1+1=2 atoms

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

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

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