Radon Atomic Number: 86Radon Atomic Weight: (222)What is Radon?Radon (atomic number 86, symbol Rn) is a gas and chemical element that is harmful for human health. In the U.S. alone, it is the main cause for over 20 thousand lung cancer deaths annually. The gas was discovered in ...
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 Radon is a radioactive chemical element with an atomic number of 86 and chemical symbol Rn. The name is derived from its association with radium. Three isotopes occur in nature, one each in the238U,235U and232Th decay series (Table R1). The most abundant is222Rn in the238U decay ...

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 from radiu...
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...
