Nuclear Fission: Unraveling the Energy of Splitting Atoms

The video explains nuclear fission, focusing on the process where unstable uranium nuclei split, releasing massive energy. Otto Hahn's discovery of fission in uranium-235 is highlighted, showing how neutron bombardment leads to a chain reaction. The chemical equation of fission is detailed, illustrating the transformation of uranium-235 to barium-141 and krypton-92, with energy and neutrons released. The video concludes with the applications of fission in nuclear bombs and reactors, emphasizing its potential for energy production.
