In an ionic compound the anion (N^(-)) form cubic close type of packing, while the cation (M^(+)) ions occupy one third of the tetrahedral voids. Deduce the empirical formula of the compound and the coordination number of (M^(+)) ions. |

Answer» SOLUTION :Number of `N^(-)` ions `=8XX(1)/(8)=1` Number of `M^(+)` ions `=(1)/(3)xx2=(2)/(3)` EMPIRICAL formula `=M_(2//3)N_(1) or M_(2)N_(3)` Coordination number of `M^(+)` is 4. |
