Radium has not its own minerals; radium exist in extremely low concentrations in uranium and thorium ores.
Uranium Oxide- U3O8
Radium is a white metal that does not occur in a free state; it must be refined from pitchblende and occurs naturally only as a disintegration product in the radioactive decay of thorium, uranium, or actinium.
Marie and Pierre Curie isolate radium. On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende.
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
No, Radon is an element. 222Rn belongs to the radium and uranium-238 decay chain, and has a half-life of 3.8235 days.
Pitchblende is a radioactive mineral composed of the mineral uraniumite. It is one of the main mineral ores of uranium.
radium
Radium is a chemical element, not a compound.
Radium is not a common commercial product.
Radium chloride, RaCl2, was the first radium compound to be prepared in a pure state and was the basis of Marie Curie's original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of radium chloride using a mercury cathode.
The first name was radium; some isotopes had in the past other names.
