WebFeb 7, 2006 · Uranium oxide was first identified in 1789 by M.H. Klaproth in the mineral pitchblende, but its distinctive property of radioactivity was discovered much later (1896) by Henri Becquerel. The subsequent discovery in 1898 of the elements polonium and radium led to the development of the radium industry, in which Canada played an important part. WebAug 21, 2024 · Krauss offered a partial explanation: that uranium was originally evenly distributed throughout (an alleged) molten earth but being a large atom, it floated toward the surface. The bias of this physicist led him to forget, apparently, that it is density, and not size, that causes things to float.
