Question 13 : stability of alkali salts depends on which of the enthalpy of formation of the salt crystal lattice of the salt formed intensity of sun rays incident on it atomic size of the metal

The stability of alkali salts depends on THE ATOMIC SIZE OF THE METAL. Salt stability refers to the ability of a salt to remain intact chemically and not decompose. Usually, metal ions with bigger atomic size form stable salts, so the higher the atomic size of the metal in the salt, the higher the stability of the salt.
