Given that interionic distance in `Na^(+), F^(-)` crystal is `2.31 Å and r_(F^(+)) = 1.36 Å`, which of the following predictions will be rightA. `r_(Na^(+))//r_(F^(-)) ~~ 0.7`B. coordination number of `Na^(+)` = coordinatin number of `F^(-) = 6`C. `Na^(+), F^(-)` will have rock salt type crystal structureD. effective nuclear charge for `Na^(+) and F^(-)` are equal |
|
Answer» Correct Answer - A::B::C `Na^(+) " & " F^(-)` are isoelectronic hence they will have same screening const (s) but not the effective nuclear charge `:. R_(Na^(+))//r_(F^(-)) ~~ 0.7` (coordination = 6, rock structure) |
