Along the period `(rarr)` atomic`//`ionic radii and metallic character decreases while `IE`, `EN` , non-metallic character and oxidising power increases. Down the group `(darr)`, atomic`//`ionic radii, metallic character and reducing character increase while `IE` and `EN` decrease. However, `Delta_(eg)H^(ɵ)` becomes less negative down a group but more negative along a period. If the ionic radii of `M^(o+)` and `X^(ɵ)` are about `135 p m`, then expected values of metallic radii of `M` and `X` should be respectively.A. `65` and `230 p m`B. `230` and `60 p m`C. `230` and `135 p m`D. `135` and `135 p m` |

Answer» Correct Answer - B Since size of `M gt M^(o+) (135 pm)` and that of `X lt X^(ɵ)(135 p m)`, therefore answer (b) is correct. |
