Maximum hydration energy is of
Correct answer: C. Al3+
- A. Na+
- B. Mg2+
- C. Al3+
Explanation
Hydration energy is the energy released when ions are surrounded by water molecules. It is influenced by the charge density of the ion, which is a function of both its charge and its size. Higher charges and smaller sizes lead to higher hydration energies because they result in stronger electrostatic attractions between the ion and the water molecules.The Al3+ ion has a charge of +3, which is higher than both Na+ and Mg2+. Additionally, it is smaller in size, resulting in a high charge density that attracts water molecules more effectively. This makes Al3+ have the highest hydration energy among the given options.In contrast, Na+ has the lowest charge and a relatively large ionic size, leading to the lowest hydration energy. Mg2+ has a higher charge than Na+ but is still less than Al3+, resulting in moderate hydration energy.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
