Brief Profile REACH registered substance factsheets C&L Inventory Biocidal active substance factsheets PACT tool In nature, radium is found in uranium and thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Since chloride ions have a charge of 1- each, it would take two chloride ions to every one radium ion to form a compound radium chloride whose empirical formula would be RaCl2. It is less soluble in water than other alkaline earth metal chlorides, a fact which is used in the first stages of the separation of radium from barium by fractional crystallization. The large quantities of material involved (tonnes of ore for milligrams of radium) favour this less costly (but less efficient) method over those based on radium bromide or radium chromate (used for the later stages of the separation). Radium Ra 223 dichloride is a radiotherapeutic drug that is approved for the treatment of male patients with symptoms of advanced prostate cancer with bone metastases. Radium has an abundance in the Earth’s crust by weight about 1 part per trillion. (a.)

Alpha particle-emitting radiopharmaceutical; contains the heavy metal radium, which mimics calcium and forms complexes with the bone mineral hydroxyapatite at areas of increased bone turnover, such as bone metastases; this causes double-strand DNA breaks that are lethal to the prostate cancer cell at the site of increased bone turnover induced by the cancer Molar mass of RaCl2 = 296.906 g/mol Convert grams Radium Chloride to moles or moles Radium Chloride to grams. Pierre Curie was appointed to the chair of physics at the Sorbonne in 1904, and Marie continued her efforts to isolate pure, non-chloride radium. The reactions with air. [2] If the presence of other anions is suspected, the dehydration may be effectuated by fusion under hydrogen chloride. radium-228 15262-20-1 Chemsrc provides Radium sulfate(CAS#:7446-16-4) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Formula: Cl2Ra .

Radium was discovered in 1898 by Marie and Pierre Curie (a Polish and French chemist, respectively) [1]. With a suspicion that the ore may contain another radioactive element, they refined several tons of pitchblende and obtained small amount of radium in the form of radium bromide. Help Key datasets.
