Why is beryllium(Hydration Enthalpy= -2494 KJ/mol) a weaker reducing agent than lithium(Hydration Enthalpy= -506 KJ/mol) even though it has a higher negative value of hydration enthalpy? Please Explain

Be is weaker reducing agent than lithium because 

Reducing agents are those compounds that loose electrons and thus help in any other compund to gain those electrons and get reduced thus after loosing one electron Li attains noble gas configuration(1S² ) whereas Be will have to break its Pseudo noble gas configuration 

 

Li- 1S²  2S¹

Be-1S² 2S²
