Helium has completely filled orbitals. hence it is chemically inert (non reactive) and is found in its pure elemental form.
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
Neon is found in its pure elemental form in nature. It is a noble gas and is very unreactive, which allows it to exist as a single atom, unlike other more reactive elements that are commonly found in compounds.
Elements in group 1 of the periodic table, such as sodium and potassium, are highly reactive due to their single valence electron. In nature, they are found in compounds as opposed to pure elemental form because they readily react with other elements to form stable compounds.
There are many nonmetals that are rarely found in their elemental form naturally. One of the more widespread of these is chlorine. Because chlorine is so reactive, it is almost always present as compounds, such as sodium chloride.
Alkali metals such as sodium and potassium are found in nature in various compounds, but they are not typically found in their pure form. They are highly reactive and readily react with other elements to form compounds.
helium does not from any compounds.

Sodium is a highly reactive element that readily forms compounds with other elements in nature. It quickly reacts with water and oxygen in the air to form compounds, such as sodium chloride (table salt) and sodium hydroxide (lye). This reactivity makes it rare to find pure sodium in its elemental form in nature.
Sodium is a highly reactive metal that readily forms compounds with other elements in nature, such as sodium chloride (table salt) and sodium carbonate (soda ash). These compounds are more stable than pure sodium metal, which is why sodium is not found in its elemental form in nature.
Elements in group 1 of the periodic table, such as sodium and potassium, are highly reactive due to their single valence electron. In nature, they are found in compounds as opposed to pure elemental form because they readily react with other elements to form stable compounds.
Chlorine is not found in the nature in his elemental form.
Sodium is to reactive to occur in its elemental form in nature. It will react rapidly with oxygen and nitrogen in air and will react violently with water. The only effective way of extracting sodium from its compounds is electrolysis.

Alkali metals such as sodium and potassium are found in nature in various compounds, but they are not typically found in their pure form. They are highly reactive and readily react with other elements to form compounds.
Most elements are sufficiently reactive so it can not exist in elemental form.
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.
