What is the co-ordination number of sodium in `Na_(2)O` ?A. 6B. 4C. 8D. 2 |
|
Answer» Correct Answer - B `Na_(2)O` has antifluorite structure `O^(2-)` ions constitute ccp lattice while `Na^(+)` ions occupy the tetrahedral voids. Each `O^(2-)` ion is in contact with 8 `Na^(+)` ions and each `Na^(+)` ion is in contact with `4O^(2-)` ions. The C.N. of sodium in `Na_(2)O=4` |
