What else can I help you with?
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.
Why are transition metals better for making jewelry than alkali 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.
Do alkali metals tarnish?
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 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.
In what way is hydrogen like the alkali metals?
Hydrogen shares some properties with alkali metals, particularly in its ability to lose one electron to form a cation with a +1 charge like alkali metals. However, hydrogen is a nonmetal and not a metal like the alkali metals.

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