| An atomic bomb is a weapon of mass destruction which uses nuclear fission to produce vast amounts of energy. |
| The element can be prepared artificially in particle accelerators and is a byproduct of nuclear fission reactions. |
| Before World War II, German chemists Otto Hahn and Fritz Strassmann discovered nuclear fission. |
| The reason is that nuclear fission occurs best with neutrons that move at relatively modest speeds, called thermal neutrons. |
| Nuclear fusion reactions are like nuclear fission reactions, therefore, in the respect that some quantity of mass is transformed into energy. |
| These engines use the heat of nuclear fission to drive steam turbines, which in turn charge the batteries. |
