The process of splitting a large nucleus into smaller ones is called nuclear ___A___ . Each of the new nuclei will have ___B___ binding energy per nucleon than the original nucleus did. When a nucleus breaks apart, two or three ___C___ are set free at the same time. These particles may cause other nuclei to split causing a chain reaction. In a nuclear reactor the chain reaction is ___D___ but in an "atomic" bomb the chain reaction speeds up producing a destructive power. Joining two light nuclei together to give a single nucleus of medium size is called nuclear ___E___. This process produces ___F___ binding energy per nucleon, and it is a very effective way to produce energy. This is the main energy source of the sun and other stars. The big problem in making this kind of energy practical is to achieve the necessary combination of ___G___ , density, and confinement time.
