Radon is a colourless, odorless, gaseous,
radioactive, nonmetallic element, with a
symbol Rn, an atomic number of 86, and an
atomic weight of 222. It is grouped with the
inert gases and was formerly considered
non-reactive, but is now known to form some
compounds with fluorine. Radon is the
densest gas known and occurs in small amounts
in spring water, streams, and the air, being
formed from the natural radioactive decay of
radium.
