A compound formed by elements A and B crystallises in cubic structure in which A atoms are at the corners of the cube while B atoms are at the centre of cubic. Formula of the compound is

A

AB

B

`AB_(2)`

C

`A_(2)B`

D

`AB_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
A atoms are at eight cornersof the cube. Therefore, the number of A atoms in the unit
cell `=(8)/(8)=1` ,
Atoms B per unit cell = 1.
Hence, the formula is AB.
