Alkali metals, such as sodium and potassium, are so reactive that they are never found as uncombined elements in nature. They readily react with other elements to form compounds.
Alkali metals and alkaline-earth metals are highly reactive and easily form compounds with elements in the environment. Consequently, they are not found in their pure form in nature. Instead, they are typically found as compounds with other elements such as oxygen or sulfur.
There are nothing uncombined. They are forming compounds inn nature.
Alkali metals are very reactive and tend to form compounds with other elements. They are not found in their pure form in nature due to their high reactivity with moisture and air. Instead, they are typically found combined with other elements in minerals such as silicates, carbonates, and chlorides.

Because these metals are very reactive and readily form compounds.
Because these metals are very reactive and readily form compounds.
The most reactive metals, such as alkali metals (like lithium, sodium, and potassium) and alkaline earth metals (like magnesium and calcium), are never found as uncombined elements in nature. Due to their high reactivity, they readily react with water, air, or other substances, forming compounds rather than existing in their elemental form. Consequently, they are typically found in mineral ores or combined with other elements.
They are very reactive.They cannot be found uncombined.
You would call them pure metals or simply elements, when a metal is mixed with another, usually for dual properties (e.g steel and aluminum alloy - in planes because it is light and strong) it is called an Alloy.
Group I elements are called alkali metals as they are generally basic in nature
alkali metals are highly reactive especially with water so they tend to form compounds in nature.
