Which one of the following has the highest hydration energy?

مندرجہ ذیل میں سے کس میں سب سے زیادہ ہائیڈریشن توانائی ہے؟
Explanation
  • Mg²⁺ has the highest hydration energy due to its small ionic size and high charge density.
  • These factors result in a strong attraction between Mg²⁺ and water molecules, leading to high hydration energy.
