 Properties > > HISTORY > > IN 1898 ERNEST RUTHERFORD, A NEW ZEALAND CHEMIST AND PHYSICIST, AND FRIEDRICH ERNST DORN SHARE CREDIT FOR DISCOVERING THE ELEMENT RADON. IN 1900, AFTER AN INSPIRED PIECE OF WORK ABOUT THE RADIOACTIVE ELEMENT THORIUM OF RUTHERFORD'S, DORN PUBLISHED A PAPER ABOUT IT. RUTHERFORD VERIFIED DORN'S WORK AND ADDED THAT THE EMMISSION-RADON- WAS QUALIFIED AS A NEW ELEMENT, JUST LIKE THE OTHER RADIOACTIVE ELEMENTS THORIUM, RADIUM, AND URANIUM. RADION WAS THE FIFTH RADIOACTIVE ELEMENT FOUND IN THE 1900. BEFORE THEN PIERRE AND MARIE CURIE NOTICED THAT THE GAS STAYED EMITTED FOR ABOUT A MONTH. SEVERAL NAMES WERE SUGGESTED FOR THIS ELEMENT AND THEY WERE ;EXRADIO, EXTHORIO, AND EXACTINIO IN 1904.
