Similarly, what is the contribution of Henri Becquerel?
Henri Becquerel, in full Antoine-Henri Becquerel, (born December 15, 1852, Paris, France—died August 25, 1908, Le Croisic), French physicist who discovered radioactivity through his investigations of uranium and other substances. In 1903 he shared the Nobel Prize for Physics with Pierre and Marie Curie.
Secondly, how did Becquerel discovered radioactivity? The Discovery of Radioactivity. In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen. Becquerel used an apparatus similar to that displayed below to show that the radiation he discovered could not be x-rays.
In this way, what did Henri Becquerel discover?
When Henri Becquerel investigated the newly discovered X-rays in 1896, it led to studies of how uranium salts are affected by light. By accident, he discovered that uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.
How did the Curies contribute to the atomic theory?
Radioactivity, Polonium and Radium Curie conducted her own experiments on uranium rays and discovered that they remained constant, no matter the condition or form of the uranium. The rays, she theorized, came from the element's atomic structure. This revolutionary idea created the field of atomic physics.
