It can't be made chemically. Neither can any other element. To generate Helium is to do it nuclearly. Either as dauther product of fission "Not a high probability", by decay i.e. alpha particals are a He atom without electrons. Lots of these around fission reactions and decay of heavy isotopes, or by fussion of two of the hydrogen isotopes deuterium and tritium. Once in the atmosphere they will rise. Due to their low mass, they reach excape velocity at ambient temperature, and are lost to space.
