Expert Answer
Atoms of element A forms CCP lattice,
No. of particles per unit cell = 4
Atoms of element B occupy edge center and body center,
No. of particles per unit cell = 3
Therefore the formula is A4B3
When all the atoms from diagonal are removed, that means 2 atoms of A and 2 atoms of B are removed.
So the formula will be A2B.
