  2. Binding energy - Wikipedia

    en.wikipedia.org/wiki/Binding_energy

    Example Level Gravitational binding energy The gravitational binding energy of an object, such as a celestial body, is the energy required to expand the material to infinity. If a body with the mass and radius of Earth were made purely of hydrogen-1, then the gravitational binding energy of that body would be about 0.391658 eV per atom.

  3. Nuclear binding energy - Wikipedia

    en.wikipedia.org/wiki/Nuclear_binding_energy

    An example that illustrates nuclear binding energy is the nucleus of 12 C (carbon-12), which contains 6 protons and 6 neutrons. The protons are all positively charged and repel each other, but the nuclear force overcomes the repulsion and causes them to stick together.

  4. Bond energy - Wikipedia

    en.wikipedia.org/wiki/Bond_energy

    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,

    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 ... For example, the fact ...

  6. Nuclear force - Wikipedia

    en.wikipedia.org/wiki/Nuclear_force

    Conversely, energy is released when a nucleus is created from free nucleons or other nuclei: the nuclear binding energy. Because of mass–energy equivalence (i.e. Einstein's formula E = mc 2), releasing this energy causes the mass of the nucleus to be lower than the total mass of the individual nucleons, leading to the so-called "mass defect". [6]

  7. Activation energy - Wikipedia

    en.wikipedia.org/wiki/Activation_energy

    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 occurs within the active site until the substrate forms to become the high-energy transition state.

  8. Valley of stability - Wikipedia

    en.wikipedia.org/wiki/Valley_of_stability

    The negative of binding energy per nucleon for nuclides with atomic mass number 125 plotted as a function of atomic number. The profile of binding energy across the valley of stability is roughly a parabola. Tellurium-125 (52 Te) is stable, while antimony-125 (51 Sb) is unstable to β− decay.
