what is the texture of radon
Radon was discovered by Robert Bowie Owens and Ernest Rutherford (GB) in 1899. The origin of the name is variation of the name of element radium; radon was called niton at first, from the Latin word nitens meaning shining. It is a colourless, odourless radioactive, heavy, noble gas that is chemically inert and non-flammable but is highly radiotoxic and carcinogen by inhalation. Radon is formed from the decay of radium in the earths crust. It is used to treat some forms of cancer. PHYSICAL PROPERTIES.
