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.
Helium does not combine with other elements and pure helium will exist by itself as elemental helium.
Helium is itself a chemical element and therefore is not found in any other chemical element.
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
Helium is one element and does not chemically react.
my guess is that its found by itself im no expert though well i guess it could be mixed in with other gasses but who knows?
No. helium is chemically inert and does not combine with other elements.
Well I believe there is approximately about 60 elements in the sun but I do know 2 of them--hydrogen and helium. ___________________________ The Sun is 70% hydrogen, 28% helium and 2% "other elements" .
Helium does not combine with other elements and pure helium will not have carbon dioxide in it.
helium's valency is zero as id does not combine with other elements
Helium is a noble gas and is generally unreactive, therefore it does not readily form compounds with other elements under normal conditions. However, it is known to form a few compounds under very high pressure and low temperature conditions with highly electronegative elements like fluorine.
because helium does not mix with other elements
helium, neon, argon, krypton, xenon and radon
