An ionic compound is made up of A cations and B anions. if A cations are present at the alternate corners and B anion is present on the body of the diagonal, what is the formula of the ionic compound ?

Explanation

To determine the formula of the ionic compound made up of A cations and B anions, we will follow these steps:

### Step 1: Understand the arrangement of ions
- The problem states that A cations are located at alternate corners of the unit cell, while B anions are positioned at the body center of the diagonal.

### Step 2: Visualize the unit cell
- Draw a cube to represent the unit cell. Mark the corners where the A cations are located. Since they are at alternate corners, only four corners will have A cations (for example, the front bottom left, back top right, etc.).
