Due to their very high reactivity with oxygen and also water, they combine to form oxides, hydroxides and from there to carbonates and others.
Because these metals are very reactive and readily form compounds.
Because these metals are very reactive and readily form compounds.
Metals that can be found uncombined in the Earth are referred to as "native metals." These metals, such as gold, silver, and copper, exist in their elemental form rather than as compounds. Native metals typically occur in their pure state due to their resistance to oxidation and corrosion, allowing them to remain uncombined with other elements in nature.
Alkaline earth metals do not exist , only alkali earth metals
No. The alkali and alkaline earth metals are very reactive.
Because these metals are very reactive and readily form compounds.
Because these metals are very reactive and readily form compounds.
No
No.
true
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.
neither. it is a noble gas
There are nothing uncombined. They are forming compounds inn nature.
Because these metals are very reactive and readily form compounds.

They are very reactive.They cannot be found uncombined.
