Radon-222 emits an alpha particle to form. RADON. Element Symbol: Rn. Atomic Number: 86. NICKI BURNS Radon exists in a number of isotopic forms and its most stable form is radon-222. Radon is Radon-222 is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the Radon, atomic number 86, is a noble gas.

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. 2020-12-10 · Radon is a gaseous radioactive element having the symbol Rn, the atomic number 86, an atomic weight of 222, a melting point of -71ºC, a boiling point of -62ºC, and (depending on the source, there are between 20 and 25 isotopes of radon - 20 cited in the What is the atomic number of radon -222? Asked by Wiki User. See Answer.

86 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). 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. particle is emitted the atomic number of the isotope de-creases by 2, and it becomes a new element.
