Which is /are correct statement about zinc blende structure ?A. zinc ions occupy half of the tetrahedral sitesB. each `Zn^(2+)` ion is surrounded by six sulphide ionsC. each `S^(2-)` ion is surrounded by six `Zn^(2+)` ionsD. it has fcc structure |

Answer» Correct Answer - A ZnS has a ccp structure . `S^(2-)` ions are present at the corners of the cube and centre of each face. `Zn^(2+)` ions occupy half of the tetrahedral sites. Each `Zn^(2+)` ion is surrounded by four `S^(2-)` ions and each `S^(2-)` ion is surrounded by four `Zn^(2+)` ions. |
