The mobilities of the alkali metal ions in aqueous solution are `Li^(+) lt Na^(+) lt K^(+) lt Rb^(+) lt Cs^(+) ` because

Comment on each of the given observations : The mobilities of the alkali metal ions in aqueous solution are Li^(+) lt Na^(+) lt K^(+) lt Rb^(+) lt Cs^(+)

Comment on each of the following observations: (a) The mobilities of the alkali metal ions in aqueous solution are Li^(+) lt Na^(+) lt K^(+) lt Rb^(+) lt Cs^(+) (b) Lithium is the only alkali metal to form a nitride directly. (c) E^(ɵ)" for "M^(2+) (aq) + 2e to m(s) (where M = Ca, Sr or Ba) is nearly constant.

The mobilities of alkali metal ions in aqueous solution increases in the order: Li^(+) lt Na^(+) lt K^(+) lt Rb^(+) . Explain.

The ionic mobility of alkali metal ions in aqueous solution is maximum for
