What is the relationship between nuclear fission, mass, and energy???

It takes energy, called binding energy, to hold nucleons together as a nucleus.
Iron has a mass number of 56 and is one of the most stable of all the elements. We say that iron has a high binding energy per nucleon.
Elements with lower and higher mass numbers per nucleon are less stable.
The total mass of a nucleus is less than the total mass of the nucleons that make up the nucleus. This difference is known as the mass defect and is equivalent to the binding energy of the nucleus, using E = mc2.
In fission, an unstable nucleus is converted into more stable nuclei with a smaller total mass. This mass defect is the binding energy that is released.
In fusion, the mass of the nucleus that is created is slightly less than the total mass of the original nuclei. Again the mass defect is the binding energy that is released, since the nucleus that is formed is more stable
