Answer 1

ANSWER

Hydration energy or enthalpy of hydration of an ion is the most amount of energy released when one mole of a particular ion dissolves in a large amount of water forming an infinite dilute solution.

Mx+(g) + nH2O (l) ------) Mx+ (aq)

Here M is a metal atom and x is the amount of positive charge,

It's quite obviously that larger the atomic size, lesser the hydration energy because for a smaller atom, it is easier for the water molecules to solvate it.

Enthalpy of hydration decreases down the group and increases across a period.

hope it helps

Answer 2

hi

buddy ✌️✌️✌️✌️

hydration energy increases as moving from left to right in a period top to bottom in a group of the modern periodic table

Brain list pls❤️❤️❤️
