This collection of elements make up Group 0 in the periodic table. They were known as inert gases for many years but that has changed with the reports of noble gas compounds. They are all gaseous elements found in the atmosphere, except for radon which is formed from the radioactive decay of uranium. The elememts are inert due to their stable electronic configuration. The gases are useful as inert atmospheres for reactions that must exclude oxygen, for balloons (helium) and for lighting displays.
