Yes. helium is found in its elemental form. it is chemically inert as it has completely filled orbitals.
Helium is a noble gas and is generally found in its elemental form in nature as it is very unreactive. It can be found in natural gas deposits and sometimes released during the extraction of natural gas.
Helium does not combine with other elements and pure helium will exist by itself as elemental helium.
Technetium is found in both in a compound and pure forms
Boron is typically found in nature as a compound rather than in pure elemental form. Examples include borax, boric acid, and various borates.
Helium found in atmosphere will have other gases as impurities. But it can be isolated by suitable method (generally by adsorption of gases) to get pure helium.
Yes,it is a pure substance but can be mixed with other gases. Like a fart. Har har har
Yes, argon is a pure element. It is a noble gas and is typically found in its elemental form in nature.
Pure helium is made of elemental helium only and is a gas at STP. It will not have air.
It can be found in both compound and pure forms. In nature, elements are often found in compounds, while in labs, they can be isolated and purified into their elemental form.
Titanium is typically found in compound form, such as titanium dioxide, rather than in pure elemental form. It is commonly extracted from minerals like ilmenite and rutile, and then processed to obtain pure titanium metal.
In atmosphere, helium is found as a mixture along with other gases. But this helium can be isolated and obtained in pure form by suitable techniques.
Phosphorus is a highly reactive element and is not typically found in its pure form in nature. It is usually found in combination with other elements in minerals or compounds. However, white phosphorus is a form of elemental phosphorus that can exist in pure form.
