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_(2)`

B

`XY_(3)`

C

`X_(3)Y`

D

XY

Text Solution

Verified by Experts

The correct Answer is:
B
No. of A stoms present per unit cell =`8times1/8=1`
No. of B atoms present per unit cell =`6times1/2=3` ltbegt `therefore` Correct composition of `A_(x)B_(y)"is"AB_(3)`
