Long Answer Type
Short Answer TypeWhy ionic conductance of alkali metal ions in aqueous solution are in the order:
Li+ < Mg + < K+ < Rb+ < Cs+ Explain ?
Why are lithium salts commonly hydrated and those of the other alkali metal ions usually anhydrous?
Comment on each of the following observations:
The mobilities of the alkali metal ions in aqueous solution are Li+ < Na+ < K+ < Rb+ < Cs+
Comment on each of the following observations:
Lithium is the only alkali metal which forms nitride directly.
Lithium is the only alkali metal which forms a nitride directly Li+ and N3- ions are very small, so they form stable Li3N.
Long Answer TypeLithium forms normal oxide, sodium forms peroxides while K, Rb and Cs form superoxides. Explain.
