Question

The number of atoms in a body centred cubic (bcc) unit cell is

Hint:

In a body-centered cubic unit cell, the number of atoms is 2.

Answer 1

Step 1: Understanding body-centered cubic (bcc).
In a bcc unit cell, there are 2 atoms: 1 at the center and 1/8 of each of the 8 corner atoms. Thus, the total number of atoms is \( 1 + 8 \times \frac{1}{8} = 2 \). Step 2: Conclusion.
Hence, the correct answer is (B) 2.
