Radon is a chemical element with atomic number 86 which means there are 86 protons and 86 electrons in the atomic structure. The chemical symbol for Radon is Rn . Radon is a radioactive, colorless, odorless, tasteless noble gas.

Radon was discovered by Friedrich Ernst Dorn at 1900 in Germany. William Ramsay and Robert Whytlaw-Gray isolated it and gave it the name 'Niton' in 1908. It has been called radon since 1923.

Radon has an atomic number of 86, so the parent isotope is represented as Th 86222Rn. We represent the alpha particle as 24He and use subtraction (222 − 4 produces an isotope of the element radon and alpha radiation. (Ra) is 88; the atomic number of radon (Rn) is 86. Radon-222 emits an alpha particle to form. RADON.

For stable elements, there is usually a variety of stable isotopes. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Mass numbers of typical isotopes of Radon are 222. Atomic Mass of Radon. Atomic mass of Radon is 222 u. The atomic mass is the mass of an atom.
