Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless [47] noble gas, occurring naturally as the decay product of uranium or thorium. Its most stable isotope, 222 Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions. It ...
