Helium is an inert gas, of which there are no known compounds. However, it is also a gas, and do to the free random movement of all gasses, and heliums relatively high average velocity as predicted by the kinetic theory of matter because of its low mass, helium molecules in a gas are moving quite rapidly. Helium will mix with all gasses, to some extend, but will mix the most at high temperatures, with gasses of similar molecular weights, in small areas.
As I know it, so far helium hasn't been combined with any elements.
Helium is an inert gas, but it does form compounds such as, HgHe, HeNe, HgHe10, WHe2, HHeF, CsFHeO and N(CH3)4FHeO.

Helium is an element.
Helium is an element. It is a noble gas. It is in the 18th period.
Helium is an element. It is a chemical element with the symbol He and atomic number 2. Helium exists as individual helium atoms, not molecules.
Yes you can mix helium and acetylene but they will not react.

Helium is an element.
Helium itself is an element and it forms no chemical compound whatsoever, therefore, it is a noble gas. The atom of Helium is so inert that it cannot even form a molecule with another atom of Helium, hence is monoatomic.
