The graph of `IE_(1)` or `Delta_(1)H_(1)^(ɵ)` versus atomic number `(Z)` is given below: Which of the following statement is correct ?A. Alkali metals are at the maxima and noble gases at the minima.B. Noble gases are at the maxima and alkali metals at the minima.C. Transition elements are at the maxima.D. Minima and maxima do not show any regular behaviour. |

Answer» Correct Answer - B Noble gases are at the maxima which have closed electron shells and very stable electronic configuration. On the other hand, minima occurs at the alkali metals and their low `IE_(1)` can be correlated with their high reactivity. |
