Radium is a silvery-white metal that is radioactive. It sends out energy in the form of rays, waves or particles. It is found in nature and can exist in several forms. Radium forms when two other chemicals (uranium and thorium) break down in most rocks and soil. Radium will undergo radioactive decay.
