  Uses of Potassium   1. It is used as a Fertilizer in agriculture. 2. It is a vital role in biological system. 3. It is a used in preparation of many useful potassium compound. 4. Potassium Hydroxide is also prepared by this which is used in the manufacture of soft soap. It is also used as an excellent absorbent of carbon dioxide. 5. Potassium nitrate is used in ceramics, colour TV tubes and fluorescent light tubes. 6. Cesium  is used in devising photoelectric cells

  Uses of sodium   1. An alloy of sodium with mercury is used for preparation of many organic compounds. 2. Liquid sodium and it's  alloy with potassium is used as a coolant in fast breeder nuclear reactor . It transfers heat from the reactor to turbine, where the heat produced the steam which is used to generate electricity. 3. Sodium with lead alloy is used to prepare tetraethyl lead which acts as an anti knock compound for petrol. 4. It is used in sodium vapour lamp. 5. Sodium is used as a reagent to detect the presence of nitrogen Sulphur and halogens in organic compound. 6. Sodium is used for preparation of useful reagents such as sodamide, Sodium Peroxide and sodium cyanate. 7. Sodium is used as a reducing agent in the extraction of Boron and silicon. 8. It is your the agent in wurtz reaction for the synthesis of many organic compound . It is also used in drying organic solvent. 9. Sodium is largely used in industry for the production of artificial rubber, dyes ,dru...

  Anomalous behaviour of Lithium is due to small size and high nuclear charge and high ionization energy . Sone Anomalous properties of lithium are :- 1. Lithium is the  only alkali metal which react with nitrogen . 2. Lithium hydrocarbon oxide exist in solution form while all other alkali metal bicarbonates are solid in nature. 3. Lithium sulphate do not form double salts. 4. Lithium chloride is deliquescent. 5. Lithium does not react with acetylene to form acetylide while other alkali metal does.
