In a face centred cubic lattice, atom `A` occupies the corner positions and atom `B` occupies the face centred positions. If two atom of `B` is missin from two of the face centred points,, the formula of the compound is `:`

A

`A_(2)B`

B

`AB_(2)`

C

`A_(2)B_(3)`

D

`A_(2)B_(5)`

Text Solution

Verified by Experts

The correct Answer is:
D
Atoms of A present at the corners
`=8xx1//8=1`
Atoms of B presents at the face centres
`=5xx1//2=5//2`
Formula of the compound
`AB_((5//2))=A_(2)B_(5)`
