Write the formula of a compound which is made of two elements A and B. Atom A forms close-packed lattice while atom B occupies all tetrahedral voids.
For every atom in a close packed structure, there are two tetrahedral voids.
Let the number of close packed spheres be N, then: The number of octahedral voids generated = N The number of tetrahedral voids generated = 2N
Therefore formula of the compound is AB2
