    The ionic conductance of alkali metal cations increases with increase in atomic mass from lithium to caesium. Explain.                    

    Answer:

                    The alkali metal cations are monovalent \[({{M}^{+}})\]Down the group, the cationic size increases and as a result, the tendency to get hydrated decreases. Since the hydration of cation decreases the ionic conductance, this means that the ionic conductance of alkali metal cations increases with increase in atomic mass.
