Hydration enthalpy of alkali metal order
WebThe ionization enthalpies of the alkali metals are considerably low and decrease down the group from Li to Cs. This is because the effect of increasing size outweighs the increasing nuclear charge, and the outermost electron is very well screened from the nuclear charge. 10.1.4 Hydration Enthalpy The hydration enthalpies of alkali metal ions WebCorrect option is D) Smaller the size of the cation, more the hydration of ion, hence the more then value of the hydration enthalpies. Now, as the down the group the size increases so the hydration enthalpies decreases, hence as the increasing order of the size of the ions is as follows: Be 2+
