Atomic mass of Radon is 222 u. 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. Radon is a naturally occurring radioisotope. Radioactivity is, and always has been a part of the earth.
Write the nuclear equation for each decay. When a mixture of trace amounts of radon-222 and fluorine gas is heated to approximately 400 °C (752 °F), a nonvolatile radon fluoride is formed. The intense α-radiation of millicurie and curie amounts of radon provides sufficient energy to allow radon in such quantities to react spontaneously with gaseous fluorine at room temperature and with liquid fluorine at −196 °C (−321 °F). Radon-222 decays at a continuous rate of 17.3% per day.

NAS estimated that radon causes about 20,000 lung cancer deaths each year. The report found that even very small exposures to radon can result in lung cancer and concluded that no evidence exists Solution for 10) Radon-222 decays at a continuous rate days?

Radon 222 Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) 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 immediate decay product of radium-226. The solid decay products of radon (Tn-222, Po-218 and Pb-214) can attach to particles in the air and travel long distances in the atmosphere. Rn-222 has a radioactive half-life of about 4 days. RISK: Lung cancer is the main health effect associated with radon exposure in humans. Radon-222: With daughters removed-1E+4: 4E-6: 1E-8--With daughters present-1E+2 (or 4 working level months) 3E-8 (or 0.33 working level) 1E-10--Page Last Reviewed Radon (Rn-222) is an odorless and colorless natural radioactive gas.
b) how long would it take the sample to decay to 10% of its original amount?
