Question

hydration enthalpy of lithium is high when compared to other alkali metals..But lithium reacts with water less vigorous than other alkali metals.why..?​

Answer 1

Answer:

The energy of atomization is very high for lithium as compared to other alkali metals. ... So, the lower density of lithium (it being lighter than other elements), and high energies of atomization and hydration make the reaction of Lithium with water less vigorous than the reaction of other alkali metals with water.
