Atomic weight of Radon is 222 u or g/mol. Radon was discovered in 1900 by Friedrich Ernst Dorn in Halle, Germany. He reported some experiments in which he noticed that radium compounds emanate a radioactive gas. In 1910, Sir William Ramsay and Robert Whytlaw-Gray isolated radon, determined its density, and determined that it was the heaviest known gas.

Radon is present in most homes and is the number one cause of lung-cancer in Radon is one of the noble gases; hence it is a chemically inert, monatomic ga What is Radon? Radon, Rn, is an extremely toxic, radioactive gas. It is atomic number 86, with an atomic weight of 222, a melting point of -71 degrees C and a Radon (Rn) is a chemically inert gas with atomic number 86 in the periodic table.

av AS Lundensia — Levels of natural radioactivity such as 222Rn (radon) and its long-lived No measurements of 222Rn in air has previously been carried out in the Arctic route of the Tundra expedition decrease from about 20·1011 atoms.l-1 at 40 °E,

Meaning of Radon. What does Radon mean? Information and translations of Radon in the most comprehensive dictionary definitions resource on the web. Thus, when an alpha particle is emitted the atomic number of the isotope decreases by 2, and it becomes a new element. In the case of radon-222, the new Radon-222 has an atomic number (Z) of 86 so an atom of radon-222 contains 86 protons in its nucleus. We could write a partial nuclear decay equation to Radon (atomic number 86) is a noble gas like helium, neon and argon that is The most abundant isotope of radon is radon-222, which undergoes decay over Aug 15, 2019 Radon has an atomic number of 86, so the parent isotope is represented as Rn 22286.

By: Kiley Poole Element: Radon Atomic Number: 86 Atomic Mass: 222 Electron Radon Atomic Mass. Radon is an element with atomic symbol Rn, atomic number 86, and 222.0. The three naturally occurring radon isotopes (222Rn, 220Rn, and 219Rn) with half-lives varying over 3 orders of magnitude are useful as tracers in many branches of geoscience.
