The reaction releases a great amount of [[binding energy]], as the binding energy of the <math>{}^{235}U</math> is much higher than the binding energy of <math>{}^{139}_{56}Ba</math> and <math>{}^{94}_{36}Kr</math> combined. This can be seen when we compare the masses of the elements involved on both sides of the equation: though the number of protons and neutrons on both sides is the same, the masses are different!
