Group Name: Noble Gas. Special Notes: Radioactive. What's in a name? Radon (Rn) Atomic Data for Radon (Rn) Atomic Number = 86 Atomic Weight = (222) Reference E95 Radon (radon 222) is the sixth element in the radioactive decay chain of 238 U, one of the major natural isotopes on earth. Radon gas poses an environmental risk because of its potential carcinogenic properties (increases in small cell and squamous cell carcinomas of the lung). Diagram of the nuclear composition, electron configuration, chemical data, and valence (outer electron) orbitals of an atom of radon-222 (atomic number: 86), the most stable isotope of this element. The nucleus consists of 86 protons (red) and 136 neutrons (orange). 86 electrons (white) successively occupy available electron shells (rings).

Radon 222 atomic number

The chemical symbol for Radon is Rn.. Atomic Mass of Radon. Atomic mass of Radon is 222 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. What is the atomic number of radon -222? Asked by Wiki User. See Answer.

17 Jan 2007 Fundamentals of radon physics: review. II. Radon 222 decay sequence Nuclides: Characterized by atomic number Z and mass number A.

The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.

Radon definition, a chemically inert, radioactive gaseous element produced by the decay of radium: Symbol: Rn; atomic number: 86; atomic weight: 222.

Density: Density at 0° Celsius. Specific Heat: Value given for gas phase. Up to date, curated data provided by Mathematica's ElementData function from Wolfram Research, Inc.
