The hydration energy of Mg2+ is greater than that of
Na+ has +1 unit charge, Mg2+ and Be2+ have +2 unit charge while Mg3+and Al3+ have +3 unit charge, therefore, hydration energy of Al3+ and Mg3+ are expected to be higher than those of Mg2+ and Be2+, which in turn, are expected to be higher than that of Na+. Further, the hydration energy of Be2+ is higher than that of Mg2+ due to its smaller size. In other words, hydration energy of Mg2+ is expected to be higher than that of Na+.
