Meitner, Otto Hahn and Otto Robert Frisch led the small group of scientists who first discovered nuclear fission of uranium when it absorbed an extra neutron; the results were published in early 1939. Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch. It is made up of nucleons called (protons and neutrons) and is surrounded by the electron cloud. The size (diameter) of the nucleus is between 1.6 fm (10−15 m) (for a proton in light hydrogen) to about 15 fm (for the heaviest atoms, such as…

He is referred to as the father of nuclear chemistry. He was awarded the Nobel Prize in Chemistry in 1944 for the… If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively. With Lise Meitner he advanced the first theoretical explanation of nuclear fission (coining the term) and first experimentally detected the fission by-products.

Photo: Archives of lished in February by the no less prestigious journal Nature. A. In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive The amount of free energy contained in nuclear fuel is millions of times the amount Uranium-238, for example, has a near-zero fission cross section for neutrons of No, said Lise Meitner; Hahn was too good a chemist for that. Lise Meitner was an Austrian-Swedish physicist who worked on radioactivity and nuclear The discovery of nuclear fission by Otto Hahn and Fritz Strassmann opened up a being nuclear fission, a term coined by Frisch, and published their paper in Nature.
