WebThe arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. … WebOct 5, 2000 · Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. This illustration shows nuclear fission of uranium-235. Nuclear Power. Nuclear bombs involve the forces — strong and weak — that hold the nucleus of an atom together, especially atoms with unstable nuclei.
