radon

Radon 86 Rn At room temp it is a gas. Mass number (22) Radon is delivered from radium It is used to treat some forms of cancer. http://www.corrosionsource.com/handbook/periodic/86.htm Discovered in 1900 by dorn. At room temp, radon is odorless and colorless. Chemical Properties- Radon does not react with any acids or bases http://web1.caryacademy.org/chemistry/rushin/StudentProjects/ElementWebSites/radon/radon_chemical_properties.htm ** Radon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying [|radium]'s decay chain. http://education.jlab.org/itselemental/ele086.html [|Radon Hazards in Uranium Mining 1960s](video) The secretory and basel cell nuclei were considered separately as potential targets ** of  ** **  biological  ** **  importance  ** for exposure to **  radon  ** daughters. http://rpd.oxfordjournals.org/cgi/content/abstract/31/1-4/405 http://speringelements.wikispaces.com/argon
 * Radon does not react with air
 * Radon does not react with water although it does dissolve slightly to the extent of about 230 cm3 kg-1 at 20°C (293 K)
 * Radon gas doesn't react with any halogens except fluorine. Radon gas reacts with fluorine to form the difluoride radon(II) fluoride, RnF2, but the compound cannot be characterized.
