The atomic number of Radon is 86. 0 0 1 Radon (Rn) has a mass number of 222 and an atomic number of 86 and decays by emission of an alpha particle. The product of this decay is - radium (Ra), with a mass number of 226 and an atomic 76 rows Radon - Atomic Number.
Up to date, curated data provided by Mathematica's ElementData function from Wolfram Research, Inc. Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless 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 lead and various other short-lived radioactive elements; radon itself is the immediate decay product of radium. Name: Radon Symbol: Rn Atomic Number: 86 AtomicWeight: 222.000000 Family: noble gases CAS RN: 10043-92-2 Description: A colorless gas State (25 °C): Gas Melting Point: 202 °K Boiling Point: 211 °K Density:.00973 g/cm 3 Oxidation states: 0 Electron Configuration: [Xe] 4f 1 4 5d 1 0 6s 2 6p 6 Radius: no data pm (Covalent) Electronegativity: 2 Radon is pumped into a small gold tube, which is then placed at the center of the tissue to be treated. With it's 3.8 day halflife, the radiation diminishes rapidly and disposal is not a big problem. The gold capsule blocks the alpha emissions from the daughter products of radon, so that the gamma rays only are used therapeutically. Answer to Radon (Rn) has a mass number of 222 and an atomic number of 86 and decays by emission of an alpha particle.

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. Since 1923, it has been called radon. Radon-222, from radium, has a half-life of 3.823 days and is an alpha emitter; Radon-220, emanating naturally from thorium and called thoron, has a half-life of 55.6 s and is also an alpha emitter. Radon-219 emanates from actinium and is called actinon. It has a half-life of 3.96 s and is also an alpha emitter. The number of protons is equal to the atomic number. Therefore radon-222 has 86 protons and carbon-14 has 6 protons.
