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.
Tarnish. Rust is for iron and its alloys alone.
Alkali metals are highly reactive. So they tend to tarnish easily.
Yes, it oxidizes very rapidly in air.
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.
Alkali metal forms Alkali while metals form bases.

The elements are the alkali metals.

Copper, silver, and brass tarnish.
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 earth metals are named after their oxides, alkaline earth.
