Radium is a chemical element; it has 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).
Jul 4, 2024 · Radium is a silvery white metal that does not occur free in nature. Its most characteristic property is its intense radioactivity, which causes compounds of the element to display a faint bluish glow in the dark.
