Definition Radon (chemical symbol Rn,222Rn) is a chemically nonreactive noble gas, and a radioactive 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 (238U), and directly issues ...
Radon (pronunciation: RAY-don) is an odorless, radioactive element that belongs to the family of noble gases and is represented by the chemical symbol Rn[1, 2]. It is colorless at room temperatures, but becomes phosphorescent when cooled below its freezing temperature and gradually turns into ...

Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive, colourless, odourless, noble gas. It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into various short...
Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as the decay product of radium. It is one of the densest substances that remains a gas under normal conditions and is considered to be a healt...
