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.

Ionic solids with Schottky defects contain in their structure

Assertion (A) : A tetrahedral void is surrounded by six spheres. Reason (R) : In ionic solids, the bigger ions form the close packed structure and smaller ions occupy the voids.

An ionic compound is formed between a metal M and a non-metal Y. If M occupies half the octahedral voids in the cubic close-packed arrangement formed by Y, the chemical formula of the ionic compound is
