WebFeb 11, 2024 · The discovery of nuclear fission was no easy feat and it came at a high cost. Nowadays, nuclear energy is often viewed with skepticism and even fear. The main danger is an uncontrolled chain reaction: As stated above, the fission not only releases energy but also neutrons. If not just one uranium atom is blasted with neutrons, but … Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei and often other particles.

WebA tremendous amount of energy is produced by the fission of heavy elements. For instance, when one mole of U-235 undergoes fission, the products weigh about 0.2 grams less than the reactants; this “lost” mass is converted into a very large amount of energy, about 1.8 × 10 10 kJ per mole of U-235. Nuclear fission reactions produce incredibly large amounts …
