Structure of a mixed oxide is cubic close-packed (c.c.p). The cubic unit cell of mixed oxide is composed of oxide ions. One fourth of the tetrahedral voids are occupied by divalent metal

A

and the octahedral voids are occupied by a monovalent metal

B

. The formula of the oxide is :

View answer and explanation

Correct option: D

A{B_2}{O_2}

Option D (

AB_2O_2

) is correct because it correctly calculates the ratio of A, B, and O atoms based on their occupancy in the ccp lattice, tetrahedral voids, and octahedral voids, respectively.
