It is colourless and odourless, and is chemically inert, but it is dangerous because it gives off alpha rays. There is a detectable amount in the atmosphere, and concentrations can build up indoors in certain localities.

Atomic number: 86 Atomic mass: 222Proton: 86 Electron: 86Neutron: 136 Density: 440Period #: 6 Group #: 18# of Isotope: 7 ex: Rn-220, Rn-219
