Periodic Table of the Elements: Radon

Name: Radon
Symbol: Rn
Atomic Number: 86
Atomic Mass: (222)
Atomic Volume: ??? cc/mol
Discovered By: Dorn
Discovery Date: 1900
Origin of Name: Radon - from Radium, Niton - (Latin) nitens (shining)
Toxicity: Dangerous, due to radioactivity.
Summary: The heaviest noble gas, and the most dense gas known. Many isotopes of Radon are formed by breakdown of radioactive elements in the ground, and are radioactive themselves. Radon can build up in unventilated areas, such as mines (especially uranium mines) and basements. It is dangerous if it or its radioactive daughter products are inhaled. Radium was once called Niton. The compound, radon fluoride, has been synthesized.
