16 Facts About Alkali metal


The bond between a water molecule and the Alkali metal ion is a dative covalent bond, with the oxygen atom donating both electrons to the bond.

All twenty stable alkali metal halides are known; the unstable ones are not known, with the exception of sodium astatide, because of the great instability and rarity of astatine and francium.

All of the stable alkali metal halides have the formula MX where M is an alkali metal and X is a halogen.

All the alkali metal halides are soluble in water except for lithium fluoride, which is insoluble in water due to its very high lattice enthalpy.

Tetraalkylammonium hydroxides, like alkali metal hydroxides, are very strong bases that react with atmospheric carbon dioxide to form carbonates.

The remaining insoluble alkali metal carbonate is then precipitated selectively; the salt is then dissolved in hydrochloric acid to produce the chloride.

The Alkali metal is produced electrolytically from a mixture of fused lithium chloride and potassium chloride.
