Hydration energy increases with:
Correct answer: A. With high charge density
- A. With high charge density
- B. Distance between nucleus and outer most electron
- C. Size of the atom
- D. None of these
Explanation
Hydration energy is the energy released when an ion or molecule is surrounded by water molecules. The hydration energy increases with higher charge density, as the stronger electric field of the ion or molecule can attract and bind more water molecules. The distance between the nucleus and the outermost electron and the size of the atom do not directly affect the hydration energy.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
