Pitchblende, a radioactive mineral, was first discovered by Johann Gottfried Gahn and K. A. Hauy in 1789. It was later identified as a uranium-rich mineral by Martin Heinrich Klaproth in 1789.
Yes, pitchblende is an important ore of uranium which also contains traces of other radioactive elements like radium and thorium. Plutonium can be produced artificially from uranium but is not naturally found in pitchblende.
The symbol of the element found in pitchblende after uranium extraction is thorium, with the chemical symbol Th. Thorium is a radioactive metal and is often found in association with uranium ores, including pitchblende.
Uranium was discovered in 1789 by German chemist Martin Klaproth, who extracted it from the mineral pitchblende. Klaproth named the new element after the planet Uranus, which had been discovered just a few years earlier.

Spangles were invented by Mars in the UK in the 1950s.
While there is no exact date, it has been a known mineral since at least the 15th century.
The color of pitchblende makes it easy to find it.
Yes. Pitchblende contains one gram of radium per seven tons. It is radioactive.
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
Yes, pitchblende is an important ore of uranium which also contains traces of other radioactive elements like radium and thorium. Plutonium can be produced artificially from uranium but is not naturally found in pitchblende.
in ore of pitchblende
Pitchblende is dangerous due to its radioactive properties. It is the primary ore of uranium and contains radium and other radioactive elements, which can emit harmful radiation. Exposure to pitchblende without proper protection can result in radiation sickness, increased risk of cancer, and other health issues. It is important to handle pitchblende with care and follow safety guidelines when working with it.

Uranium
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.
To determine the amount of oxygen combined in the sample of pitchblende, we use the chemical formula of pitchblende, which is U3O8. The molar ratio of uranium to oxygen in U3O8 is 3:8. Given that there are 1.8 tons of uranium in the sample, we calculate the amount of oxygen by multiplying 1.8 tons of uranium by the ratio of oxygen to uranium (8/3). This yields approximately 4.8 tons of oxygen combined in the sample of pitchblende.
