      (III) Among the alkali metals, only L i forms a stable nitride by ...

      C s + is more highly hydrated than the other alkali metal ions. 2. Among the alkali metals L i, N a, K and R b, lithium has the highest melting point. 3. Among the alkali metals only lithium forms a stable nitride by direct combination. Out of these statements:

      The ionic radii of alkali metal ions in water (hydrated radii) are in ...

      The ease of adsorption of the hydrated alkali metal ions on an ion-exchange resins follows the order : (1) K++. Na++ Rb++ Li++ (2) Na++ Li++ K++ Rb++(3) Li++ K++ Na++ ...

      The ionic mobility of alkali metal ions in aqueous solution is

      The mobility of metal ions in an aqueous medium (L i ⨁, N a ⨁, K ⨁, R b ⨁) in an electric field, follows the order: View Solution The ionic mobility of alkali metal ions in aqueous solution is maximum for:K^+Rb^+Li^+Na^+

      What is the order of mobilities of the alkali metal ions in ... - Toppr

      As smaller the size of the ion, larger the charge of the ion hence greater the hydration and smaller ionic conductance and mobility of the ion. So the increasing order of mobility the alkali metal ions in aqueous solution is L i + < N a + < K + < R b + < C s +. Hence option D is correct.

      The correct order of hydration enthalpies of alkali metal ions is:

      Reason The hydration enthalpies of alkali metal ions decrease with increase in ionic size. Assertion Lithium salts are mostly hydrated.

      Ionic mobility of which of the following alkali metal ions is the ...

      All the alkali metal ion exists as hydrated ions M + (H 2 O) n in it's an aqueous solution. The degree of hydration decreases as the ionic size increases when we go down the group. Since the mobility of ions is inversely proportional to the size of their hydrated ions, the increasing order of ionic mobility is. L i + < N a + < K + < R b +

      Alkaline earth metal ions are strongly hydrated than alkali ... - Toppr

      alkali metals do not form dipositive ions while alkaline metals form. why?

      Among the alkali metal ions in aqueous solution, which is the

      (I) C s + ion is more highly hydrated than other alkali metal ions. (II) Among the alkali metals L i, N a, K, and R b, L i has the higher melting point. (III) Among the alkali metals, only L i forms a stable nitride by direct combination.

      Why are lithium salts commonly hydrated and those of the other …

      Among alkali metal ions, Li(I) has smallest size due to which it can easily polarize water molecules. Li salts get bonded to water of crystallization. The lithium chloride contains 2 water molecules per mole of LiCl. The other alkali metals being bigger in size cannot easily polarize water molecules.

      The mobilities of the alkali metal ions in aqueous solution are

      The mobilities of the alkali metal ions in aqueous solution are L i + < N a + < K + < R b + < C s + because : greater is the degree of hydration, lesser is the mobility in aqueous medium; larger the size of cation, greater is the mobility in aqueous medium; larger the size of cation, lesser is the mobility in aqueous medium
