Electron binding energy, more commonly known as ionization energy, [3] is a measure of the energy required to free an electron from its atomic orbital or from a solid. The electron binding energy derives from the electromagnetic interaction of the electron with the nucleus and the other electrons of the atom , molecule or solid and is mediated ...
The bond dissociation energy (enthalpy) [4] is also referred to as bond disruption energy, bond energy, bond strength, or binding energy (abbreviation: BDE, BE, or D). It is defined as the standard enthalpy change of the following fission: R—X → R + X. The BDE, denoted by Dº(R—X), is usually derived by the thermochemical equation,
Nuclear binding energy in experimental physics is the minimum energy that is required to disassemble the nucleus of an atom into its constituent protons and neutrons, known collectively as nucleons. The binding energy for stable nuclei is always a positive number, as the nucleus must gain energy for the nucleons to move apart from each other.
where E binding is the binding energy (BE) of the electron measured relative to the chemical potential, E photon is the energy of the X-ray photons being used, E kinetic is the kinetic energy of the electron as measured by the instrument and is a work function-like term for the specific surface of the material, which in real measurements ...
Binding affinity carries a huge importance in medicinal chemistry, as drugs need to bind to the protein effectively within a desired range. An exothermic binding process with a favorable enthalpy is considered a desirable characteristic for specific protein binders, as it indicates strong potential for optimization and high selectivity.

This is possible due to a release of energy that occurs when the substrate binds to the active site of a catalyst. This energy is known as Binding Energy. Upon binding to a catalyst, substrates partake in numerous stabilizing forces while within the active site (e.g. hydrogen bonding or van der Waals forces). Specific and favorable bonding ...
The electron affinity (E ea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e − → X − (g) + energy. This differs by sign from the energy change of electron capture ionization. [1]
The gravitational binding energy of a system is the minimum energy which must be added to it in order for the system to cease being in a gravitationally bound state.
