Uraninite
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.
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
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.
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
"Illuminate your world with Radium!" "Shine bright like Radium!" "Glowing brilliance with Radium." "Radiant energy, powered by Radium."
The first name was radium; some isotopes had in the past other names.
No plural for radium.
Radium primarily forms compounds with oxygen, such as radium oxide (RaO), radium peroxide (RaO2), and radium hydroxide (Ra(OH)2). It can also form compounds with other elements, such as radium chloride (RaCl2) and radium sulfate (RaSO4). These compounds are generally highly radioactive due to the nature of radium as a radioactive element.
