text: For α decay to be spontaneous, the decay products must have smaller mass than the parent.
text: This decay, called spontaneous fission, happens when a large unstable nucleus spontaneously splits into two (or occasionally three) smaller daughter nuclei, and generally leads to the emission of gamma rays, neutrons, or other particles from those products.
text: Radioactive decay is spontaneous and does not required an input of energy to occur.
text: Nuclides with atomic numbers of 90 or more undergo a form of radioactive decay known as spontaneous fission in which the parent nucleus splits into a pair of smaller nuclei.
text: This decay is spontaneous and releases energy, because the products have less mass than the parent nucleus.
