Combination of hydration energy and ionization energy

(A) The stability of the oxidation states of lanthanoids in aqueous solution is determined by the balance between the energy required for ionization (ionization enthalpy) and the energy released during hydration (hydration enthalpy). $Ln(s) \rightarrow Ln^{3+}(aq) + 3e^-$. The overall stability depends on the sum of these energy terms.
