Xenon is a Noble Gas and is inert. So are Helium, Neon, Argon, Krypton, and
Radon.
The Halogens are among the most reactive elements known.... Fluorine,
Chlorine, Bromine, Iodine and Astatine. They are never found as elements in
nature, always compounds. The usually form salts with the Alkali Metals;
Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. The name
Halogen, in Greek means 'Salt Former'. When the Halogens are isolated in
the lab, they are gases at room temperature (or higher), except Bromine
(liquid). Iodine never forms a liquid, but goes directly from gas to solid
or solid to gas.  Hope this helps.
