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++ ...
Why alkali metals do not from di-positive ions - Toppr
Alkali metals have only one electron in their outermost energy levels , so (they can loose one electron to) they form a mono positive ion only . That's why alkali metal do not from dispositive …
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 …
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 …
(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 …
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 …
Among alkali metals in aqueous solution - Toppr
Among alkali metals in aqueous solution $$ Li^+ $$ ion has the lowest mobility b ecause of smallest size among alkali metals, $$ Li^+ $$ ions are most highly hydrated in aqueous …
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.
Explain the following: Why alkali metals do not form dipositive ions?
The alkali metals after loss of one electron achieve stable configuration of inert gases. The removal of second electron requires very high energy. Hence, alkali metals do not form …
Ionic mobility of which of the following alkali meta ions is lowest ...
