Answer 1

A compound is formed by elements A and B. This crystallizes in the cubic structure when atoms A are at the comers of the cube and atoms B are at the centre of the body. The simplest formula of the compounds is AB.

Explanation:

'A' atoms are at eight comers of the cube.

Therefore, the number of 'A' atoms in the unit cell = `8/8` = 1

Number of 'B' atoms per unit cell = 1

Hence, the formula is AB.
