Which two groups of elements are never found uncombined in nature?

group 1 elements


What group of metals is so reactive that the metals are never found as uncombined elements in nature?

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.


What group of metals is so reactive that the metals are never found as?

The group you're thinking of is group 1, the alkali metals. They include sodium and potassium, and you're right, they are so reactive that they do not exist by themselves. They only exist in compounds with other elements.


Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?

Group 1 (alkali metals) and Group 17 (halogens) in the periodic table contain elements that are highly reactive and are never found in their free state in nature. Alkali metals readily react with water or air, while halogens are highly reactive nonmetals that form compounds with other elements quickly.


What two elements are never found as elements in nature because they combine so easily with other substances?

Fluorine and francium are two elements that are never found as elements in nature due to their high reactivity. Fluorine readily reacts with almost all elements, while francium is extremely radioactive and decays quickly into other elements.


Why do metals at the top of the activity series never found in the nature as free elements?

because they are too reactive to exist on their own, they bond with other elements in nature to satisfy their need for electrons


Which groups of metals are most reactive therefore never being found free in nature?

Group 1 and group 2 metals


Which group of elements occur only as compounds in nature because they are extremely reactive?

The alkali metals (Group 1 elements) such as sodium, potassium, and lithium occur only as compounds in nature because they are highly reactive and readily form compounds with other elements or molecules. They are never found in their pure elemental form in nature.


What element is never found in nature as a pure native element?

Fluorine is never found in nature as a pure native element due to its high reactivity. It typically forms compounds with other elements such as in minerals like fluorite.


Element never found in its free state?

Fluorine is an element that is never found in its free state in nature due to its high reactivity, forming compounds with other elements very quickly.


Which group had elements on the periodic table that almost never react?

Noble gases or group 18 elements


Why is group 1 element occur as salt in nature and never found in their element state?

They're too reactive. They will react with oxygen or moisture in the air, so they can't exist as pure elements unless protected. The usual method is to submerse them in oil.
