Where was protactinium found?
The first isotope of protactinium (234mPa) was discovered by Kasimir Fajans and Otto Gohring in 1913 (Germany). The isotope 231Pa of protactinium was discovered by Austrian/Jewish physicist Lise Meitner and by Otto Hahn, a German physical chemist in 1918 and simultaneously by Frederick Soddy and John Cranston (England). Protactinium exist in extremely low concentrations in uranium ores (approx. 3 mg/kg).

When was uranium discovered?
The discovery of the element is credited to the German chemist Martin Heinrich Klaproth. While he was working in his experimental laboratory in Berlin in 1789. He found an uranium oxide (which he had named after the planet Uranus which had recently been discovered) in pitchblende ores. The pure element was isolated in 1841 by Eugene Melchior Peligot.
How was uranium discoverd?
In 1789 Klaproth discovered a new mineral; he make a confusion between the element and mineral and considering pitchblende the element named this uranium.In 1842 Peligot showed that this mineral is an oxide and separated uranium as a chemical element, a metal.

The name of a German chemist and physicist who split the uranium atom in 1939 and also considered as the father of atom bomb?
Otto Hahn, Fritz Strassmann and Lise Meitner in 1939; I consider that the expression father of the atomic bomb is not adequate.
Was uranium discovered in Germany?
Martin Heinrich Klaproth, a German apothecary, considered in 1789 that a mineral from Joachmow is a new metal. In fact it was only an oxide.In 1842 Eugene Melchior Peligot, French chemist, separated uranium as a pure metal.
Who first found uranium?
Martin Heinrich Klaproth, a German chemist, discovered uranium (as an oxide) in 1789, in minerals from Johanngeorgenstadt (Germany) and Jachimov (Czech Republic).
Which country first found uranium?
Martin Heinrich Klaproth, a German chemist, discovered uranium (as an oxide) in 1789, in minerals from Johanngeorgenstadt (Germany) and Jachimov (Czech Republic).
How is uranium discovered?
Uranium has discovered as an oxide by the German chemist Martin Heinrich Klaproth in 1789 studying a mineral from Joachimov (now in Cech Republic). As a pure metal uranium was prepared by Peligot in 1841.
What year did Becqueral discover the radioactive element uranium?
Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (a mix of uranium oxides) in 1789. Klaproth confused the oxide with the metal. In 1841 the French chemist Peligot isolated uranium as a pure metal element. Henry Becquerel (also a Frenchman) discovered the natural radioactivity of uranium in 1896.
What year was uranium discovered?
In 1789 Martin Heinrich Klaproth discovered an uranium oxide. In 1841 Eugène-Melchior Péligot obtained the first pure uranium metal.
What was uranium named after?
The name of the chemical element uranium is derived from the name of the planet Uranus.
Who was discovered uranium?
Uranium was discovered as an oxide in 1789 by the German chemist Martin Heinrich Klaproth in a mineral (probable pitchblende) from Joachimov (now in Czech Republic); the pure metal was obtained in 1841 by Eugene Peligot in France.
How did they discover uranium?
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.
