FullText Abstract The various steps in our knowledge of the physical and chemical properties of radium which have led to its use in the treatment of cancer, and the successive improvements in its mode of application are of much interest; but since they are not essential to the present purpose...
Radium is the heaviest known alkaline earth metal and is the only radioactive member of its group. Its physical and chemical properties most closely resemble its lighter congener, barium.[3](p 112) Pure radium is a volatile silvery-white metal, although its lighter congeners calcium, strontium...

Radium metal may be prepared byelectrolyticreduction of its salts, and it displays high chemical reactivity. It is attacked bywaterwith vigorous evolution ofhydrogenand by air with the formation of the nitride. It occurs exclusively as the Ra2+ionin all its compounds. The sulfate, RaSO4, is ...
All three forms of uranium have the same chemical and physical properties, but have different radioactive properties. ... As uranium decays naturally over time, it releases radiation and forms new elements like radium, lead, and radon gas. Radium occurs naturally from the radioactive decay of ...
In general, radium is expected to form the same type of compounds as its barium analogue. However, there is no record of the preparation of such compounds ormeasurements of their properties, both physical and chemical. Perhaps this is due to the difficulty in handling radioactive226Ra compounds...
Possible relationships between Ra and Ra activity concentrations, the Ra/Ra activity ratio and physical and chemical properties of produced water were statistically evaluated; no linear correlations were found.doi:10.1016/j.apradiso.2005.11.015M.S. Al-Masri...

Chemical PropertiesBrilliant-white solid. Luminescent, turns black on exposure to air. Soluble in water with evolution of hydrogen; forms water-soluble compounds. Decays by emis- sion of α-, β-, and γ-radiation. Bone-seeking when taken into the body. ...
