The free element has the third-highest melting point and highest boiling point of any element. ... Radon is a chemical element with symbol Rn and atomic number 86.
Radon has no stable isotopes; its longest-lived isotope, 222 Rn, has a half-life of 3.8 days and decays to form helium and polonium, which ultimately decays to lead. [13] Oganesson also has no stable isotopes, and its only known isotope 294 Og is very short-lived (half-life 0.7 ms). Melting and boiling points increase going down the group.
