SUMMARY
The hydration energy of ions decreases as the size of the ion increases due to the reduction in the charge to size ratio. Larger ions possess a lower charge density, which results in weaker electrostatic interactions with water molecules. This phenomenon is explained by Coulomb's law, which illustrates how the force between charged particles diminishes with increased distance. Consequently, smaller ions with higher charge to size ratios exhibit greater hydration energies.
