Bcoz, alkali metals ve an unpaired electron in the 'ns' orbital, which gets filld wen it iz ionically bonded...
Alkali metals exist only as salts.
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
Alkali metals are not ferromagnetic. All materials are affected by magnetic fields to some degree, however. Also, alkali metals could be made into electromagnets insofar as they are conductive, though this would not be practical.
The solubility of carbonate salts varies depending on the specific salt and the conditions. Generally, carbonates of alkali metals like sodium and potassium are soluble in water, while carbonates of transition metals are not very soluble.
Yes, alkali metals like sodium and potassium are found in nature. They are often found in minerals and salts, and they are quite reactive due to their tendency to lose one electron and form positive ions.
Alkali metals exist only as salts.
Li, Na, K, NH4
These salts are weak electrolytes: examples are acetates, formates etc. of alkali metals.
Those salts which can dissolve in water.because water is a solvent and salts are solute.
The products of the reactions are ionic salts.
Halogens, such as chlorine, iodine or fluorine.

Chromates of Alkali metals are soluble, but most other chromates are insoluble
Examples: chlorides, sulfates, carbonates of alkali metals, nitrates etc.
Halogens ions from alkali metals halides have a corrosive effect on materials.
