Energy obtained from fusion and fission reactions is based on differences in the nuclear binding energy. The mass of the products of a fusion reaction is smaller than the mass of its reactants. The ...

The reason why opposite processes release energy can be understood by examining the binding energy per nucleon curve. Both fusion and fission reactions shift the size of the reactant nuclei towards ...

There are a number of different nuclear fusion reactions happening in the Sun. The simplest is when four hydrogen nuclei become one helium nuclei.
