In a face centred cubic lattice, atom `A` occupies the corner positions and atom `B` occupies the face centred positions. If one atom of `B` is missin from one of the face centred points,, the formula of the compound is `:`A. `AB_(2)`B. `A_(2)B_(3)`C. `A_(2)B_(5)`D. `A_(2)B`

Answer» Correct Answer - 3
Effective no. of A atoms `=(1)/(8)xx8=1`
Effective no. of B atoms `=(1)/(2)xx5`
(One is missing) `=(5)/(2)`
Therefore formula is `(A_(1)B_((5)/(2))=A_(2)B_(5))`
