A compound is formed by elements A and B . This crystallises in the cubic structure where the A atoms are the corners of the cube and B atoms are at the body centres . The simplest formula of the compound is

A

`A_(8)B_(4)`

B

`AB_(6)`

C

AB

D

`A_(6)B`

Text Solution

Verified by Experts

The correct Answer is:
C
AB compound crystallises in the cubic structure. A atoms are at the corners of the cube. So , No. of a atoms per unit cell `=8cc1//8=1`.
No . Of B atoms per unit cell =1
`therefore` Simplest formula of the compound = AB.
