Question

Atoms X and Y form bcc crystalline structure. Atom X is present at the corners of the cube and Y is at the centre of the cube. What is the formula of the compound?

Answer 1

Atoms X and Y form bcc crystalline structure. Atom X is present at the corners of the cube Atom Y is present at the centre of the cube.

No of atoms of X in the unit cell = \(\frac{N_c}{8}\,=\frac{8}{8}\) = 1

No of atoms of Y in the unit cell = \(\frac{N_b}{1}\,=\frac{1}{1}\) = 1

Ratio of atoms X : Y = 1 : 1

Hence formula of the compound = XY
