In a solid AB, A atoms have a ccp arrangement and B atoms occupy all the octahedral sites. If all the face-centred atoms along one of the axes passing through body centres are removed, then what will be the resultant stoichiometry of compound ?

Explanation

To solve the problem, we need to determine the resultant stoichiometry of the compound AB after removing certain atoms from the solid structure. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Initial Arrangement
In the solid AB:
- A atoms are arranged in a cubic close-packed (CCP) structure, also known as face-centered cubic (FCC).
- B atoms occupy all the octahedral sites.

### Step 2: Calculate the Initial Number of A Atoms
