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

A compound formed by elements X and Y crystallises in the cubic structure, where X - atoms are at the corners of a cube and Y - atoms are at the centres of the body. 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:
A
On the given unit cell, number of X-atom = `8xx1/8=1` and number of Y-atom = 1. Thus the ratio of X and Y-atom = 1 : 1. Thus the formula of the compound is XY.
