Give different applications of alkali metals and their compounds.
Answers
➡These metals are soft, shiny, silvery white elements.
➡They are highly reactive with water. They are mostly not found in free nature as they react quickly and vigorously. Some of these metals are stored in kerosene or other mineral oils.
➡They oxidize rapidly in air. Due to oxide coating, its bright, shiny luster is hidden. When the coating is cut off with a knife, the shiny metal will be clearly visible.
➡Luminant, colorful flame is produced by them when burned with oxygen.
➡These have low ionization enthalpy (heat evolved when an atom gets ionized).
➡These are strong reducing agents.
➡They are malleable and ductile.
Softness of the element down the group increases due to increasing atomic number because the metallic bond will decrease with increase in atomic size.
➡The ionization energy of group 1A elements decreases down the group.
➡These are good conductors of heat and electricity.

Hey friend...
Here is your answer...
Alkali metals are:-
Lithium, sodium, potassium, rubidium, cesium, and francium.
They are metals with lusture, soft, white, reactive with acids and base.
Uses :-
1.Lithium is used in lubricants
2.Most of the Potassium is used in making the fertiliser.
3.Sodium nitrite is a principle ingredient in gunpowder
