What is Nuclear Binding Energy?
Nuclear binding energy is the energy required to completely separate a nucleus into its constituent protons and neutrons, or equivalently, the energy released when the nucleus is assembled from those nucleons. It arises from the strong nuclear force. The binding energy per nucleon peaks at iron-56 (approximately 8.8 MeV/nucleon), which explains why fusion releases energy for elements lighter than iron and fission releases energy for elements heavier than iron.
