Radium, Ra Boiling Point: 1737 degrees celcius Melting Point: 700 degrees celcius Density: 5000 kg/m 88 Protons, 88 Electrons, and 138 Neutrons Atomic Mass: 226g Atomic Number: 88

electron configuration of radium bValence Electrons: 2 It was found in 1898 by Marie and Pierre Curie in North Bohemia. It was mined in Australia from 1954 to 1961. Physical properties are it has no specific hardness. Chemical properties are it is a good conductor of heat and electricity. In radiums ore it is much more radioactive than Uranium. Its compounds have a faint blue glow when they are in the dark. An example of a radium compound is Radium Chloride. Two common chemical reactions of Radium are it decomposes in water and it turns black when it is exposed to air. It used to be used in luminous paints, clocks, and nuclear panels but it was outlawed because the paint caused the death of many people. Its value for laboratory experiments is up to $40,000,000 a pound.
