An element occurs in bcc structure. How many atoms are present in its unit cell ?

Explanation

To determine the number of atoms present in a body-centered cubic (BCC) unit cell, we can follow these steps:

### Step 1: Understand the BCC Structure
The BCC structure has atoms located at specific positions within the unit cell. In a BCC unit cell, there are atoms at the eight corners and one atom at the center of the cube.

### Step 2: Calculate the Contribution from Corner Atoms
Each corner atom is shared among eight adjacent unit cells. Therefore, the contribution of each corner atom to the unit cell is:
\[
