A compound formed by elements X and Y cr...

A compound formed by elements `X` and `Y` crystallises in a cubic structure in which the `X` atoms are at the corners of a cube and the `Y` atoms are at the face centres.The formula of the compound is

A

`XY_(3)`

B

`X_(3)Y`

C

XY

D

`XY_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Contribution by X atoms at the corners of the cube `=1//8xx8=1`
Contribution by Y atoms at the centre of each face `=1//2xx6=3`
:. Ratio of X and Y `=1:3`
Formula of cube `=XY_(3)`
