Radium chloride is an inorganic compound with the chemical formula Ra Cl 2. It is a radium salt of hydrogen chloride. It was the first radium compound isolated in a pure state. Marie Curie and André-Louis Debierne used it in their original separation of radium from barium.
Radium bromide is the bromide salt of radium, with the formula RaBr 2. It is produced during the process of separating radium from uranium ore . This inorganic compound was discovered by Pierre and Marie Curie in 1898, and the discovery sparked a huge interest in radiochemistry and radiotherapy .
Additionally, radium phosphate, radium oxalate, and radium sulfite are probably also insoluble, as they coprecipitate with the corresponding insoluble barium salts. [5] The great insolubility of radium sulfate (at 20 °C, only 2.1 mg will dissolve in 1 kg of water) means that it is one of the less biologically dangerous radium compounds. [6]

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).
Different methods of applying radium had been tested, which fell into two categories: the use of radium emanation (now referred to as radon), and the use of radium salts. One method using emanation was through inhalation, where it was mixed with air. Radium inhalation had been most studied in Germany, where regular inhalation institutes were ...
Radium carbonate is a chemical compound of radium, carbon, and oxygen, having the chemical formula Ra C O 3. It is the radium salt of carbonic acid. It contains radium cations (Ra 2+) and carbonate anions (CO 2− 3). This salt is a highly radioactive, amorphous, [4] white powder that has potential applications in medicine.
My go-to method for years has been (for two of us): five large eggs, one large yolk, salt and pepper, and a splash of cream. I cook the whisked eggs in butter, over the lowest heat possible on the ...
