Radon - Periodic Table of Videos: Con Martyn Poliakoff. Radon was traditionally obtained by the radioactive decay of radium and was the subject of a fierce competition between Ernest Rutherford and William Ramsay to be the first to isolate it.
Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It is a colorless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. Learn more ab
The chemical behaviour of radon is similar to that of a metal fluoride and is consistent with its position in the periodic table as a metalloid element. Element Properties atomic number 86 stablest isotope (222) melting point −71 °C (−96 °F) boiling point −62 °C (−80 °F...
Definition Radon (chemical symbol Rn, 222 Rn) is achemically nonreactive noble gas, and aradioactive chemical element with an atomic number of 86 (in the periodic table) and an atomic weight of 222. It is one of the products of spontaneous uranium decomposition ( 238 U), and directly ...

half-life of 3.82 days. A natural source of radiation found in most soils and groundwater, radon poses a serious health threat if inhaled. Atomic number 86; melting point -71°C; boiling point -61.7°C; density of gas 9.73 grams per liter; specific gravity (solid) 4. SeePeriodic Table...
The noble gases are the group of elements—helium, neon, argon, krypton, xenon—in the rightmost column of the periodic table of the elements, those which have “filled” outermost shells of electrons (two for helium, eight for the others). This configuration of electrons results in a neutra...
