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. Which of the following isoelectronic species has lowest `IE_(1)` ?A. `K^(o+)`B. `Ca^(2+)`C. `S^(2-)`D. `Cl^(ɵ)` |
|
Answer» Correct Answer - C `S^(2-)` have the largest size among the given isoelectronic ions, so it has the lowest `IE_(1)`. |
