- This invisible something was named radiation, and it was determined that an element that gives off radiation is a radioactive element. Today, we know uranium as one of the radioactive elements. For his discovery of radioactivity, Becquerel was awarded the 1903 Nobel Prize for physics. Review: Henri Becquerel discovered the radioactive properties of uranium when he stored a piece with some film and notched an image on the film.

Marie Curie: Facts & Biography View full size image. Marie Curie was a physicist and chemist and a pioneer in the study of radiation. She and her husband, Pierre, discovered the elements polonium and radium. Together, they were awarded the Nobel Prize for Physics in 1903, and she received another one, for Chemistry, in 1911. Her work with radioactive materials doomed her, however. She died of a blood disease in 1934.

- Radium, in the form of radium chloride, was discovered by Marie Curie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later.26 Ra is the most stable isotope of radium and is the last isotope in the (4 n + 2) decay chain of uranium-238 with a half-life of over a century. Its immediate decay product is the dense radioactive noble gas radon, which is responsible for much of the danger of environmental radium.

Benchmarks: Henri Becquerel discovers radioactivity on February 26, 1896 This discovery of spontaneous “radioactivity” (a term coined by Becquerel’s doctoral student, Marie Curie) eventually earned Becquerel a Nobel Prize for Physics in 1903, which he shared with Marie Curie and her husband Pierre Curie.enchmarks: Henri Becquerel discovers radioactivity on February 26, 1896. Credit: A photographic plate made by Henri Becquerel shows the effects of exposure to radioactivity. A metal Maltese cross, placed between the plate and radioactive uranium salt, left a clearly visible shadow on the plate.

- The process of nuclear fission was discovered in 1938 by Otto Hahn and Fritz Strassmann and was explained in early 1939 by Lise Meitner and Otto Frisch. The fissionable isotope of uranium, U-235, can be split by bombarding it with a slow, or thermal, neutron.

- H. Becquerel discovered that uranium was radioactive, i.e. was emitting energy which was unknown at the time. Marie Curie and Pierre Curie did further work on radioactivity a…nd discovered new elements, radium and polonium which were also radioactive. Ernest Rutherford and his collaborator Soddy explored radioactivity systematically and discovered several new radioactive elements.

It's Elemental Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.

- Radon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying radium 's decay chain. Originally named niton after the Latin word for shining, nitens, radon has been known as radon since 1923. Today, radon is still primarily obtained through the decay of radium.

Curies isolate radium A+E Networks. On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende. One year after isolating radium, they would share the 1903 Nobel Prize in physics with French scientist A. Henri Becquerel for their groundbreaking investigations of radioactivity.

James Chadwick - Facts When Herbert Becker and Walter Bothe directed alpha particles (helium nuclei) at beryllium in 1930, a strong, penetrating radiation was emitted. One hypothesis was that this could be high-energy electromagnetic radiation. In 1932, however, James Chadwick proved that it consisted of a neutral particle with about the same mass as a proton. Ernest Rutherford had earlier proposed that such a particle might exist in atomic nuclei.

Radium Radium was discovered by Marie Sklodowska-Curie and her husband Pierre Curie on 21 December 1898, in a uraninite (pitchblende) sample. While studying the mineral earlier, the Curies removed uranium from it and found that the remaining material was still radioactive.
