  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...

  Diagonal relationship between Lithium and magnesium   Lithium and magnesium so similar properties due to save polarising power or ionic potential. 1.Lithium and magnesium  chlorides are covalent, deliquescent  and soluble in alcohol and pyridine. 2. Carbonates of Lithium and magnesium decompose on heating. 3. Both Lithium and magnesium react with nitrogen to form nitrides. 4. Bicarbonates of Lithium and magnesium are more solution in water than carbonate.
