By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Metals need to be protected against rust and tarnish because rust and tarnish eat metals.
Lithium, Sodium and potassium are all soft metals which can be cut easily with a knife. This freshly cut piece is a shiny silver color which tarnishes quickly to a dull grey as these metals react with the oxygen and water in air. Sodium tarnishes quicker than Lithium and potassium tarnishes quicker than sodium. Thus, Potassium tarnishes quicker than lithium and not the other way around.
Alkali metal forms Alkali while metals form bases.

bcoz sodium is a alkali metal these metals when xposed to air they tarnish rapidly due to the formation of oxides on surface Save
Alkali metal forms Alkali while metals form bases.
Alkali metals are the most reactive metals.

Alkali metals are very reactive metals.
Alkali metals are known for there ability to destroy blood plankta inside your blood stream (been 3 recorded deaths so far). Also transition metals are known for there low electronegativity and there ability to produce amphiprotic substances. Just so many awesome reasons why you cant pass transition metals.
