Why are alkali metals not found in nature?

Text Solution

Verified by Experts

Alkali metals are highly eletropositive and extremely reactive elements. Thus, they easily react with atmospheric oxygen and carbon dioxide. These metals have a high tendency to lose electrons to form cations because of their low ionisation potential. For this reason, they readily react with highly electronegative elements or radicals to form compounds. So, alkali metals are not found in free state in nature.
