A compound is formed by elements a and b

Asked by admin @ 12/08/2021 in Chemistry viewed by 341 People

A compound formed by element A and B, crystallizes in the cubic structure. When atoms

of A are at the corners of the cube and B atoms are at the face centres, the formula of the
compound is

Answered by admin @ 12/08/2021

Contribution of Atom A at the corners to the unit cell = 8 × 1/8 = 1.
Contribution of Atom B at the face centers to the unit cell = 6 × 1/2 =3.
So, ratio of the two atoms present in the compound = A:B = 1:3.
So, the formula of the compound = AB3.
