    • Increase in atomic number increases the size of the element which in turn outweighs increasing nuclear charge. Therefore the outermost electron experiences strong screening effect from the nuclear charge.
    • The energy released as a result of the formation of new bonds between ions and water molecules is called hydration enthalpy.
    • In alkali metals the hydration enthalpies decreases with the increase in ionic sizes.
      Li+> Na+ > K+ > Rb+ > Cs+
