Question

An alloy of gold & cadmium crystallises with a cubic structure in which gold atoms occupy the corners % cadmium atoms fit into the face centre . Assign formula for this alloy .

Open in App

Solution

The formula for the alloy will be AuCd_3.
Contribution of Au ions present at the corners of the cube = 1/8 x8 = 1
Contribution of Cd ions present at the faces of the cube = 6 x 1/2 = 3
Thus, the formula becomes AuCd₃
