I)in a period as go from left to right the electrons are added to the same shell hence nuckear charge increases so the radii decrease from alkali metals to alkaline earth metals

ii) in alkali metals aftervremoving one electron they gain noblegas configuration so to remive electron from that is difficult so IP2 is very high .whereas in alkaline earth metals after removing one electron they still have to one more elecron to get noble gas configuration so its easy to remove the electron hence IP2 is less

iii)large hydration energy of alkaline earth metals ions because of their much largervcharge to size ratio ,exert a much stronger electrostatic attraction on thevoxygen of water molecule..
Hope...you may understand..
