The elements belonging the same group have similar properties. We have to pass 2, 8, 8, 18, 18, 32 and 32 elements before we come across an element with similar properties. The repetition of the elements with similar properties in the order of increasing atomic number as in the periodic table is called periodicity of properties and 2,8, 18 and 32 are called magic numbers. Causes of periodicity of properties:…

Factors affecting the magnitude of solvation or hydration energy
Definition of solvation energy: When a gaseous cation or a gaseous anion interacts with the solvents forming a solvated cation or a solvated anion and in this process energy is liberated, which is called solvation energy. If water is used as a solvent, then gaseous cation or gaseous anion forms hydrated ion, and the liberated energy associated with this process is termed as a hydration energy. M + (g) +…
