They are helium atoms and have all the properties of helium. Helium is mono-atomic [as are all of the noble gases] Non-noble gases [those gases that react with other elements/compounds] are diatomic meaning that in the gaseous state the atoms are paired on to another.
Helium is a monatomic gas. That is its atoms do NOT combine with anything. It is the most unreactive of all elements.
No, helium is not a compound. It is a monatomic gas, meaning it consists of single atoms of helium.
No. Helium atoms in the gas state are neutrally charged.
No, Helium is an inert or "noble" gas. It does not make chemical combinations with any other atoms.
The gas formed when hydrogen atoms fuse is helium. Stars do this.
