the first ionization enthalpies of alikali and alkaline earth metals a

1.	the first ionization enthalpies of alikali and alkaline earth metals are generally low.however enthalpies of ll-A group elements is generally higher than l-A group elements. why?
Answer» Answer: II-A elements have generally 2 ELECTRONS at outermost orbit and are little stable than I-A METAL. Hence, ALKALINE earth elements have more enthalpies GREATER than alkaline elements. Explanation:
