The ionisation enthalpy of alkaline earth metals is

The second ionisation enthalpy of the alkaline earth metals is __________ than their first ionisation enthalpy.

Assertion : The alkaline earth metal hydroxides are more basic than the corresponding alkali metal. Reason : The ionisation enthalpies of alkaline earth metals are much lower than those of alkali metals.

The second ionisation enthalpy of an alkaline earth metal is higher than its first ionisation enthaply. Why is it so ?

The second ionisation enthalpies of alkaline earth metals are much lower than those of the corresponding alkali metals. Explain.
