Radon 222 atomic number

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. (a) radium (Ra), with a mass number of Element 86 of Periodic table is Radon with atomic number 86, atomic weight 222.

particle is emitted the atomic number of the isotope de-creases by 2, and it becomes a new element. In the case of radon-222, the new element formed is called polonium-218. Also, the mass number decreases by 4. Alpha particles are very large by radiation standards, and they can do a lot of damage to sensitive biological tissue, mainly by knocking

Asked by Wiki User. See Answer. Top Answer. Wiki User Answered 2012-12-07 10:59:59. The atomic number of Radon is 86.

For example, hydrogen contains only one proton and has an atomic number of one (Z=1). Helium has two protons; carbon has 6, oxygen has 8, uranium has 92, radon has 86, and so on. Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas.
