A solid crystal is composed of X, Y and Z atoms. Y atoms are occupying 50% of octahedral voids, where as X atoms are occupying the 100% tetrahedral void with Z atoms in ccp array arrangement, then the rational formula of the compound in the given crystal is (A) X 8 Y 2 Z 4 (B) X 5 Y 10 Z 8 (C) X 4 YZ 2 (D) X 16 Y 4 Z 8
Z atoms are in ccp array so no of Z atoms=4no of octahedral voids=4no of tetrahedral voids=8so no of Y atoms=2no of X atoms=8so formula X8Y2Z4 that means X4YZ2 correct answer is CSher mohammadFaculty askiitians
