Hey buddy here is ur answer !!!
》The alkali metal ion exist as hydrated ions M+(H2O)n in the aqueous solution.
》 The degree of hydration, decreases with ionic size as we go down the group..
Hence Li+ ion is mostly hydrated
》e.g. [Li(H2O)6]+
》Since the mobility of ions is inversely proportional to the size of the their hydrated ions, hence the increasing order of ionic mobility is
Li+ < Na+ < K+ < Rb+ < Cs+ < Fr+
Hope so it helps you:—))
