Unreactive

Summary: The noble gases take part in very few Chemical Reactions. Scientists say they are unreactive. From top to bottom of the group, the noble gases get slightly more reactive. - Helium is at the top of Group 0. As far as we know, it never takes part in chemical reactions. - Xenon is at the bottom of Group 0. It is very unreactive. However, it does form Compounds with fluorine and oxygen.
