An ionic compound has a unit cell consisting of A ions at the corners of a cube and B ions on the centers of the faces of the cube .The empirical formula for this compound would be

A

AB

B

`A_(2)B`

C

`AB_(3)`

D

`A_(3)B`

Text Solution

Verified by Experts

The correct Answer is:
C
Contribution by A ions at the corners of the cube `=8xx1//8=1` . Contribution by B ions at the centres of all the six faces of the cube `=6xx1//2=3`
`:.` Formula of the compound `AB_(3)`
