Fissio nuclear
WebApr 1, 2024 · Fusion. Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products. WebAnswer (1 of 7): A nuclear fission bomb needs a switched neutron source. Before a fission bomb is detonated, neutrons will appear in its core now and then, mainly from spontaneous fission of the fissile material, but also from cosmic rays and the mild radioactivity of almost everything. A neutro...

Enrico Fermi and his colleagues in Rome studied the results of bombarding uranium with neutrons in 1934. Fermi concluded that his experiments had created new elements with 93 and 94 protons, which the group dubbed Ausonium and Hesperium …
WebNuclear fission happens naturally every day. Uranium, for example, constantly undergoes spontaneous fission at a very slow rate. This is why the element emits radiation, and why … WebNuclear 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. The fission process often produces ...
