Radon (Rn)

Radon is the 86th element in the periodic table and has a symbol of Rn and atomic number of 86. It has an atomic weight of (222) and a mass number of 193. Radon has eighty-six protons and one hundred seven neutrons in its nucleus, and eighty-six electrons in six shells. It is located in group eighteen, period six and block p of the periodic table. Colorless radioactive gaseous element, belongs to the noble gases. Of the twenty known isotopes, the most stable is Rn-222 with a half-life of 3.8 days. Formed by the radioactive decay of Radium-226. Radon itself decays into Polonium. Used in radiotherapy. As a noble gas, it is effectively inert, though radon fluoride has been synthesized. First isolated in 1908 by Ramsey and Gray.

History

Radon was discovered in 1900 by Friedrich Ernst Dorn in Halle, Germany. He reported some experiments in which he noticed that radium compounds emanate a radioactive gas. In 1910, Sir William Ramsay and Robert Whytlaw-Gray isolated radon, determined its density, and determined that it was the heaviest known gas. The name was derived from radium; called niton at first, from the Latin word nitens meaning shining

Discoverers	Fredrich Ernst Dorn
Discovery Location	Germany
Discovery Year	1898
Etymology (Name Origin)	Variation of the name of another element, radium.
Pronunciation	RAY-don (English)

Radon is highly radioactive and a carcinogen

Upon condensation, radon glows because of the intense radiation it produces

Uses

Radon is used in hydrologic research that studies the interaction between ground water and streams. Radon has been produced commercially for use in radiation therapy. Radon has been used in implantable seeds, made of gold or glass, primarily used to treat cancers. Used to treat some forms of cancer.

Sources

Formed from the decay of radium in the earths crust.
