Electron in a sentence

Electron-electron interactions in atoms If there is more than one electron around the atom, electron-electron-interactions raise the energy level.

The atom of another element (usually nonmetal), whose electron affinity is positive, then accepts the electron(s), again to attain a stable electron configuration, and after accepting electron(s) the atom becomes an anion.

The original ionization event liberates one electron, and each subsequent collision liberates a further electron, so two electrons emerge from each collision: the ionizing electron and the liberated electron.

Also observed, for charged pions only, is the very rare "pion beta decay " (with branching fraction of about 10 −8 ) into a neutral pion, an electron and an electron antineutrino (or for positive pions, a neutral pion, a positron, and electron neutrino).

Because the binding energy of the electron is much less than the mass of the electron, nuclei that can undergo β + decay can always also undergo electron capture, but the reverse is not true.

Characteristic X-rays are emitted when the electron beam removes an inner shell electron from the sample, causing a higher-energy electron to fill the shell and release energy.

Electron elastic scattering In the elastic scattering interaction, a neutrino collides with an atomic electron and imparts some of its energy to the electron.

Electron therapy can treat such skin lesions as basal-cell carcinomas because an electron beam only penetrates to a limited depth before being absorbed, typically up to 5 cm for electron energies in the range 5–20 MeV.

Fundamentally, an atomic orbital is a one-electron wave function, even though most electrons do not exist in one-electron atoms, and so the one-electron view is an approximation.

In electron capture, an inner atomic electron is captured by a proton in the nucleus, transforming it into a neutron, and an electron neutrino is released.

In the case of an electron, if it is initially "observed" at a particular slit, then the observer–particle (photon–electron) interaction includes information about the electron's position.

In this model the electron cloud of a multi-electron atom may be seen as being built up (in approximation) in an electron configuration that is a product of simpler hydrogen-like atomic orbitals.

Lithium has a low ionization energy and readily gives up its lone valence electron to a fluorine atom, which has a positive electron affinity and accepts the electron that was donated by the lithium atom.

These changes in speed can be due to electrostatic interactions between particles (ion to ion, ion to electron, electron to electron).

This is because the outermost electron of the alkali metals is in a different electron shell than the inner electrons, and thus when it is removed the resulting atom has one fewer electron shell and is smaller.

This spacing is called the electron affinity (note that this has a different meaning than the electron affinity of chemistry); in silicon for example the electron affinity is 4.05 eV.

Relativistic effects then force the electron to emit high-energy photons not in any random direction, but along the original course of the beam of electrons (hence the name: Free-Electron Laser—FEL).

As quantum physics reveals, the newly energized electron leaves an "electron hole" behind.

But Electron can also pose a significant security risk because of how easily Electron-based applications can be modified without triggering warnings.
