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.
What else can I help you with?
Do the alkali metals have the ability to tarnish?
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
What happens when the alkali metals react with chlorine?
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.
What are the colours of alkali metals?
Alkali metals such as lithium, sodium, potassium, rubidium, cesium, and francium typically exhibit a silvery metallic color. When cut, their freshly exposed surfaces tend to tarnish quickly, forming dull oxides that can range in color from white to gray.
What are more reactive alkali metals or alkline earth metals?
alkali metals
What family of elements is in the leftmost column?
alkali metals
Do the alkali metals have the ability to tarnish?

Which groups of elements are silvery-white metals that tarnish when exposed to air?
The elements are the alkali metals.
What are the colours of alkali metals?

How chemically active are alkali metals?
Alkali metals are the most reactive metals.
What are more reactive alkali metals or alkline earth metals?
alkali metals
Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
How are alkali metals different any from other metals?
Alkali metals are very reactive metals.
How do alkali metals react with other alkali metals?
They don't
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
What are the group of soft silvery reactive metals known as?
alkali metals
What are the property of alkali metals?
highly reactive, tarnish easily, low melting points, soft, low density, some have weak radiation also it is very flammable in water
