They are very reactive.They cannot be found uncombined.
There are nothing uncombined. They are forming compounds inn nature.
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.
Because these metals are very reactive and readily form compounds.
Some metals are found uncombined in the Earth's crust because they have low reactivity and do not readily react with other elements to form compounds. These metals include gold, silver, and copper, which are typically found in their pure metallic form in nature.

Never, these metals are very reactive.
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.
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.
is hydrogen uncombined in nature
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.
