In a close packed structure of an ionic compound anions B form the close packed lattice and the cations A occupy octahedral voids.Predict the formula of the compound.

In an ionic compound, oxide ions have ccp arrangement Cations A are present in one eighth of the tetrahedral voids whilst cations B occupy half of the octahedral voids.the empirical formula of the compound is

A compound is formed by two elements X and Y . Atoms of the element Y (as anion) make ccp and those of element X (as cation) occupy all the octahedral voids. What is the formula of the compound?

In certain solid, the oxide ions are arranged in ccp. Cations A occupy (1)/(6) of the tetrahedral voids and cations B occupy one third of the octahedral voids. The probable formula of the compound is
