They are highly reactive metals, reacting with water (explosively) and air. In nature they simply would not last very long at all!
i don't know. but i am in chemestry and i need to know.
what i know so far is, that the are found in common substances.
if you are a chemestry teacher you should know! :)
plese get back to me by december 13th. i have a short exam then.
but i also know that They are unstable in air and in water (moisture).

Are alkali metals always found pure in nature?
Alkali metals are not found as pure elements in nature.
Are alkali metals readily available in nature?
The alkali metals are all very recative and are not found free in nature (pure elemental form) but are always found as compounds. (minerals)
Are alkali metals found as pure elements in sea water?
Alkali metals exist only as salts.
Why are alkali metals found in many common substances but rarely found in pure form?
Alkali Metals are rarely found in pure form, and if they are they are normally stored under oil, because they react with water and water vapor in the air very violently. They explode if placed in water because they have one electron in their outer energy level and they want to give it away so badly. But if they are bonded with other elements, particularly non-metals, they lose that high reactivity.

Why are group 1 metals called alkaine metals?
They are actually called the alkali metals. They are called the alkali metals because many of the compounds they form are bases (alkaline) and in pure form they will react with water to produce strong bases.
Why alkalai metals are found as compounds?
Alkali metals, such as sodium and potassium, are highly reactive and tend to combine quickly with other elements in nature to form compounds. This is because they have only one valence electron, which they easily lose to achieve a stable electron configuration. Therefore, it is rare to find pure alkali metals in their elemental form in nature.
Which metals are not found in ores?
There are a lot more than five. For example, all the alkali and alkaline earth metals are not found naturally in pure form but occur only in compounds. It's actually unusual for a metal to exist in pure form in nature; most of them occur only in compounds.
Why are alkali metals rarely found as pure elements?
They are highly reactivated. they are reacting with other compounds.
Which native metals are found in a pure form?
Gold
Is an metal acidic or alkaline?
Pure metals are neither, no pure element is and acid or an alkali, it is only compounds made from elements that have this property. When metals form compounds those compounds are typically alkaline.
Explain why alkali metals are not found in free state in nature?
Alkali Metals belong to group 1 of periodic table. They have one electron in last or valence shell and are highly electropositive and have low value of Ionisation enthalpy. So the removal of last electron to form a cation(positively charged ion) is very easy and needs less energy as compared to other elements. As a result of this Alkali metals are highly reactive and readily form ionic compounds. Due to this they react with other elements or compounds and form ionic compound. Hence, they are found in their compounds and not in free state.
