binding energy

n 1. (General Physics) the energy that must be supplied to a stable nucleus before it can undergo fission. It is equal to the mass defect 2. (General Physics) the energy required to remove a particle from a system, esp an electron from an atom

Binding Energy

binding energy

[′bīn·diŋ ¦en·ər·jē] (physics) Abbreviated BE. Also known as total binding energy (TBE). The net energy required to remove a particle from a system. The net energy required to decompose a system into its constituent particles.

Energy, Binding

(also separation energy), the energy of any bound system of particles (such as an atom) equal to the work required to decompose the system into constituent particles such that they are an infinite distance from each other and cannot interact. It is a negative quantity, since energy is released in the course of the formation of the bound state, and its absolute value characterizes the bond strength (for example, the stability of nuclei).

According to the Einstein relation, the binding energy is equivalent to the mass defect Δm: ΔE = Δmc², where c is the velocity of light in a vacuum (seeMASS DEFECT). It is determined by the type of interaction between the particles in a given system. Thus, the binding energy of the nucleus is due to the strong interactions of the nucleons in the nucleus (in the more stable nuclei of intermediate atoms, the specific binding energy is ~8 × 10⁶ electron volts [eV]). The energy may be released when light nuclei fuse into heavier ones, as well as upon the fission of heavy nuclei, which is explained by the decrease of the specific binding energy with increasing atomic number.

The binding energy of electrons in an atom or molecule is determined by the electromagnetic interactions, and for each electron it is proportional to the ionization potential; it is equal to 13.6 eV for an electron of the hydrogen atom in the normal state. These same interactions are responsible for the binding energy of atoms in a molecule or crystal. In the case of the gravitational interaction, the binding energy is ordinarily small; however, it may be of considerable magnitude for certain celestial objects, such as black holes.

binding energy

energy that would be released if a particular atomic nucleus were formed through the combination of individual protons and neutrons. Synonym(s): fusion energy

binding energy

The minimum energy needed to dissociate an atomic nucleus into neutrons and protons—neutron binding energies (BEs) remove neutrons from the nucleus; proton BEs remove protons from the nucleus; electron BEs remove electrons.
