Radon is a chemical element ; it has symbol Rn and atomic number It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only radon has a sufficiently long half-life 3. Radon's most stable isotope , radon, has a half-life of only 3. Radon will be present on Earth for several billion more years, despite its short half-life, because it is constantly being produced as a step in the decay chain of uranium , and that of thorium , each of which is an extremely abundant radioactive nuclide with a half-life of several billion years. The decay of radon produces many other short-lived nuclides , known as "radon daughters", ending at stable isotopes of lead. Radon occurs in minute quantities as an intermediate step in the decay chain of thorium, also known as the thorium series , which eventually decays into lead , which is stable.
