Binding energy refers to the minimum energy required to disassemble a system of bound particles into its individual components. This concept is most commonly applied in the context of atomic nuclei, where it represents the energy needed to separate a nucleus into its constituent protons and neutrons. Conversely, it is also the energy released when these nucleons bind together to form a nucleus.

The binding energy of a nucleus is directly related to its stability. Nuclei with higher binding energies per nucleon are generally more stable. This relationship is often visualized through the binding energy curve, which plots the binding energy per nucleon against the mass number of the nucleus. The curve shows that light nuclei have low binding energies, which increase as the mass number grows. However, beyond iron and nickel, the binding energy per nucleon begins to decrease, indicating that heavier nuclei are less stable.

Nuclear reactions, such as nuclear fission and fusion, involve changes in binding energy. Fission splits a heavy nucleus into lighter ones, and fusion combines light nuclei into a heavier one. In both cases, the resulting particles have a higher binding energy per nucleon than the original particles, leading to the release of a significant amount of energy. This energy release is a direct consequence of the difference in binding energies.
