Metal M ions form accp structure. Oxide ions occupy ½ octahedral and ½ tetrahedral voids. What is the formula of the oxide? (a) MO (b) MO2 (c) MO3 (d) M2O3 |

Answer» Answer is (d) M2O3 Metal M ions form ccp structure. Let number of ions of M be : x No. of tetrahedral voids = 2x No. of octahedral voids = x Number of oxide ions will be 1/2 x + ½ (2x) = 3/2 x Formula of oxide = MxO3/2 x = M2O3 |
