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 :
a reactive metal

Text Solution

Verified by Experts

Element I. Since it has low first ionisation enthalpy and a very high value for second ionisation enthalpy, it is expected to be an alkali metal. It should be Li (lithium) as it forms predominantly stable covalent halides of the formula MX.
