Binding energy refers to the minimum energy required to disassemble a system of bound particles into its constituent parts. It is a fundamental concept in physics, particularly in nuclear physics and particle physics. For atomic nuclei, binding energy represents the force that holds protons and neutrons together within the nucleus. A higher binding energy per nucleon generally indicates a more stable nucleus.

The binding energy is also equal to the energy released when the system is formed from its components. This energy difference arises from the mass defect, a consequence of Einstein's famous equation E=mc², where mass is converted into energy or vice versa. When a nucleus is formed, its mass is slightly less than the sum of the masses of its individual protons and neutrons, with the difference in mass accounting for the binding energy.

In the context of chemical bonds, binding energy describes the strength of the attraction between atoms in a molecule. It is the energy needed to break a specific bond. This concept is crucial in understanding chemical reactions, molecular stability, and the properties of different substances. The units for binding energy are typically Joules (J) or electron-volts (eV).
