A compound formed by element A and B crystallize in the cubic structure where A atoms are at the corners of a cube and B atoms are at the centre of the body. The formula of the compounds is

A

`A_(2)B_(3)`

B

`AB_(2)`

C

`AB_(3)`

D

AB

Text Solution

Verified by Experts

The correct Answer is:
D
`therefore`No.of atoms of element A per unit cell =8 (at corners)`times1/8=1`.
No. of atoms of B in one unit cell=1 (present in the body centre of the cube).
`therefore` the number of atoms of elements A and B per unit is one each.
Hence the formula is AB.
