WebRadium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2 ). WebHenri Becquerel discovered mysterious "rays" from uranium. 1897: Marie Curie named the mysterious rays "radioactivity." 1901: Henri Alexandre Danlos and Eugene Bloch placed radium in contact with a tuberculous skin lesion. 1903: Alexander Graham Bell suggested placing sources containing radium in or near tumors. 1913
