Which mineral is radium obtained?
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
When did Marie curie find pitchblende?
It exposed or marked Film In boxes
Why is radium difficult to extract from pitchblende?
The principal problem is simply that so much ore is required to provide small amounts of radium. About one ton of pitchblende yields about one seventh of a gram of radium.
What radioactive element was extracted from carnotite and pitchblende?
the main element extracted was radium
Where did martin klaproth discover uranium?
In pitchblende from Joachimow (now in Czech Republic), 1789
Is contact with pitchblende dangerous?
Yes. Pitchblende contains one gram of radium per seven tons. It is radioactive.
What property makes it easy to find pitchblende?
The color of pitchblende makes it easy to find it.
Is Pitchblende an ore of plutonium?
No. Pitchblende is an ore of Uranium. It's been a long time since plutonium occured in nature.
Which mineral is radium obtained?
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
How do you find radium?
in ore of pitchblende
What is a blackish mineral that is a type of uraninite?
pitchblende
What radioactive element is constracted from carnotite and pitchblende?
Uranium
What weapon which used the main extraction of pitchblende as fuel?
Pitchblende is uranium ore, so any nuclear weapon which used uranium in some form or other (tamper, core, used with plutonium, secondary casing) would need uranium, which is initially obtained from the mining and refining of pitchblende, for example, Little Boy.
How many metric tons of oxygen are combined in a sample of pitchblende that contains 1.8 tons of uranium?
0.242 t of oxygen; but the value is only an approximate because the pitchblende is not only pure UO2.
What kind of ore is urananite?
Uraninite, AKA pitchblende, is an ore of uranium.
When did Marie curie find pitchblende?
It exposed or marked Film In boxes
What special property does the mineral pitchblende have?
Pitchblende (or uraninite) is an important mineral of uranium and is of course radioactive.The hardness on the Mohs scale is 5-6.The density is high, between 10 and 11 g/cm3.
