1.	The ions O^(-2),F^(-),Mg^(2+) and Al^(3+) are isoelectronic. Their ionic radii show
Answer» a decrease from `O^(2-)` to `F^(-)` and then increase from `Na^(+)` to `AL^(3+)` a significant increase from `O^(2-)` to `Al^(3+)` a significant decrease from `O^(2-)` to `Al^(3+)` an increase from `O^(2-)` to `F^(-)` and then decrease from `Na^(+)` to `Al^(3+)` Answer :C
