Question
In a face centred cubic lattice, atom A occupies the corner positions and atom B occupies the face centre positions. If one atom of B is missing from one of the face centred points, the formula of the compound is
Options
A.AB2
B.A2B3
C.A2B5
D.A2B
Solution
Effective no.of A atoms = 
Effective no.of B atoms =
× 5 (One is missing) = 
Therefore formula is A1B5/2 = A2B5
Effective no.of B atoms =
× 5 (One is missing) = Therefore formula is A1B5/2 = A2B5
