It is found in the atmosphere.
There are several isotopes of Helium and they have different numbers of neutrons. The simplest and most common is Helium-4 which has two neutrons
Stars contain hydrogen, helium and a little iron.
Helium is a noble gas and is inert, meaning it does not react with common compounds like oxygen, nitrogen, or carbon dioxide. Helium is chemically stable and does not form compounds easily due to its full outer electron shell.
