Tarix
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.
