Who first experimented with radioactive uranium?

Answer 1

1896, Antoine Henri Bequerel: discovering of the radiocativity of uranium 1938, Otto Hahn and Fritz Strassmann: Discovering of the uranium fission with neutrons 1940, Gheorghi Florov and Konstantin Petrjak: discovering of the spontaneous fission of uranium

Answer 2

Martin Heinrich Klaproth discovered in 1789 (not invented !) the first uranium mineral - an uranium oxide. In 1841 Eugene Melchior Peligot obtained uranium as pure metal.
Uranium is a natural chemical element, discovered in 1789 by Martin Heinrich Klaproth and obtained as a pure metal in 1841 by Eugene Melchior Peligot. Of course, uranium is not an invented material.
Uranium was not invented, it is a natural chemical element. Discoverad as an oxide by Klaproth in 1789, isolated as pure element by Peligot in 1841, identified as radioactive element by Bequerel in 1896.

Answer 3

The discovery of radioactivity in uranium is credited to Antoine Henri Becquerel in 1896. He accidentally discovered that uranium salts emitted rays that could fog photographic plates. This accidental discovery paved the way for further research into the field of radioactivity.
