Chemicals/Radons

Radon is a radioactive, colorless, odorless, tasteless noble gas.

Gases
Radon is, under standard conditions, gaseous and easily inhaled, and therefore a health hazard.

Radon is "one of the noble gases."

The molecules and RnXe were found to be significantly stabilized by spin-orbit coupling.

Radon is a colorless, odorless, and tasteless gas and therefore is not detectable by human senses alone. At standard temperature and pressure, it forms a monatomic gas with a density of 9.73 kg/m3, about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m3. It is one of the densest gases at room temperature and is the densest of the noble gases.

Liquids
Although colorless at standard temperature and pressure, when cooled below its freezing point of 202 K, it emits a brilliant radioluminescence that turns from yellow to orange-red as the temperature lowers. Upon condensation, it glows because of the intense radiation it produces. It is sparingly soluble in water, but more soluble than lighter noble gases. It is appreciably more soluble in organic liquids than in water. Its solubility equation is as follows,


 * $$\chi = \exp(B/T-A)$$,

where $$\chi$$ is the molar fraction of Radon, $$T$$ is the absolute temperature, and $$A$$ and $$B$$ are solvent constants.

Alloys
Radon carbonyl (RnCO) has been predicted to be stable and to have a linear molecular geometry.
