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.
- In 1789 the German Martin Heinrich Klaproth discovered uranium as an oxide in the mineral pitchblende from Joachimow.
- In 1841 the French Eugene Melchior Peligot obtained uranium as a pure metal.
In 1789 Martin Heinrich Klaproth, a German chemist, analyzed a new mineral and has confused this mineral (an oxide) with a new metal. The name uranium was proposed also by Klaproth, derived from the name of the planet Uranus discovered by Herschel in 1781.
In 1841 a French scientist, Eugene Péligot isolated the pure metallic element uranium.
Discovered as an oxide by Martin Klaproth in 1789, first separated as a pure metal by Eugene Melchior Peligot in 1841.
Uranium was discovered as an oxide in 1789 by Martin Heinrich Klaproth after the study of a mineral from Joachimov.
Uranium as a pure metal was obtained by Eugene Peligot in 1841.

- They discovered that radiations are emitted from the uranium atom (and not from the molecule containing uranium) and are dependent on the quantity of uranium. - They discovered polonium and radium in uranium minerals.
Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
