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

Answer» Correct Answer - A The ionic radii of alkali metal ions are larger than those of the corresponding alkaline earth metal ions . Also ionic radii increase down the group . Therefore , the ionic size radii decrease in the order : `Na^(+) gt Li^(+) gt Mg^(2+) gt Be^(2+) ` i.e., option (a) is correct . |
