The first ionization enthlpies of alkali metals decreases down the group because of ________.

The first ionization enthlpies of alkali metals decreases down the group because of ________.

The ionisation enthalpy values of alkali metals indicate that lithium should be poorest reducing agent because of its high ionization energy. However, it is the strongest reducing agent among alkali metals. This may be explained because of:
