The first (`Delta_(i), H_(1)`) and the second (`Delta, H_(2)`) ionisation enthalpies (in kJ mo`l^(- 1)` ) and the `(Delta_(eg)H`) electron gain enthalpy (in kJ mo`l^(-1)` ) of a few elements are given below :

Which of the above elements is likely to be :
the least reactive element?

Text Solution

Verified by Experts

Element II. Since it has the least first ionisation enthalpy and a low value for electron gain enthalpy, it is expected to be the most reactive metal. It should be an alkali metal.
