Nuclear reactions result in tremendous amounts of what

The best word to complete the thouht of the statement is "energy". Nuclear reactions result in tremendous amounts of energy. There are two types of nuclear reaction namely fusion and fission reactions. Fusion reaction is a type of nuclear reaction where two or more nuclei combine or collide to form an element with a higher atomic number. This happens when the collision is in a very high speed. In this process, some of the matter of the fusing nuclei is converted to energy. Fission, on the other hand, takes place in any of the heavy nuclei after capture of a neutron. It breaks down a nuclei into two.
