A compound is made up of two elements A & B, having cubic structure. Atoms A occupy corners as well as face centre whereas atoms B occupy edge centre as well as body centre. What is formula of the compound ?

Explanation

To determine the formula of the compound made up of elements A and B with the given cubic structure, we will follow these steps:

### Step 1: Identify the positions of atoms A and B in the unit cell
- Atoms A occupy the corners and face centers of the cubic unit cell.
- Atoms B occupy the edge centers and the body center of the cubic unit cell.

### Step 2: Calculate the number of A atoms in the unit cell
- **Corners:** There are 8 corners in a cube, and each corner atom contributes \( \frac{1}{8} \) of an atom to the unit cell.
