Dear user
Normal formula of compound is Na4Cl4
now on removing all the atoms from 1 body diagonal,
lost atoms = 4 Cl at corner, 2 Na from edge centre, 2 Cl from face centre, 1 Na from body centre
so loss in Cl = 4*1/8 + 2*1/2 = 1.5
and loss iin Na = 2*1/4 + 1*1 = 1.5
so new formula = Na2.5Cl2.5
so formula will remail same
It will remain AB
