The set representing the correct order of ionic radius isA. `Li^(+) gt Be^(2+) gt Na^(+) gt Mg^(2+)`B. `Na^(+) gt Li^(+) gt Mg^(2+) gt Be^(2+)`C. `Li^(+) gt Na^(+) Mg^(2+) gt Be^(2+)`D. `Mg^(2+) gt Be^(2+) gt Li^(+) gt Na^(+)` |

Answer» Correct Answer - B Is the correct order. In moving from left to right radii decreases while they increase downwards. `Li^(+)` and `Mg^(2+)` are diagonally related. The correct order is : `Na^(+) gt Li^(+) gt Mg^(2+) gt Be^(2+)` |
