Radon

= = =**Radon (Rn)** =



Atomic Number: **86** Atomic Mass: **222** Protons: **86** Neutrons: **86** Electrons: **136** Melting point: **-71° Celsius** Boiling point: **-61.8° Celsius** Normal phase: **Gas** Cost= **$4 for mCi**

Classification: **Non metal** Belongs to the Noble Gas family

Origin of Name: From radium, once called niton from latin word nitens, meaning 'shining' Discovered by: Fredrich Ernstdorn in **1819** ====Interesting Information: ====
 * 1) Obtained through the decay of radium
 * 2) It is a colorless, odorless, radioactive gas
 * 3) When cooled to its solid state, radon glows yellow
 * 4) Glow becomes orange-red as the temperature is lowered
 * 5) Small amounts of radon are sometimes used to treat some forms of cancer
 * 6) Since radon is a gas, it is easily inhaled and living tissue is directly exposed to the radiation
