unique ideas for elementary student awards do something new and creative this year by awarding your elementary students with unique student awards hopefully one or more of these awards made you think of a specific student
C. Fission: may create radioactive nuclei, may undergo a chain reaction Fusion: energy source for stars Fission and fusion: large amount of energy produced
An atom contains protons and neutrons in its central nucleus. In fission, the nucleus splits, either through radioactive decay or because it has been bombarded by other subatomic particles known as neutrinos. The resulting pieces have less combined mass than the original nucleus, with the missing mass converted into nuclear energy. Controlled fission occurs when a neutrino bombards the nucleus of an atom, breaking it into two smaller, similarly-sized nuclei. Each newly freed neutron can go on to cause two separate reactions, each of which can cause at least two more.
