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

B

`XY_(2)`

C

`X_(2)Y_(3)`

D

`XY_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
No. of atoms `=(1)/(8)=1`
No. of Y atoms `=6xx(1)/(2) =3`
Hence, the formula is `XY_(3)`
