Electrons that are bound to atoms possess a set of stable energy levels, or orbitals, and can undergo transitions between them by absorbing or emitting photons that match the energy differences between the levels.

Electrons are bound by electromagnetic wave mechanics into orbitals around atomic nuclei to form atoms, which are the building blocks of molecules.

Electrons remain bound to atoms but are able to transfer to adjacent atoms.

Electrons from ionized atoms interact mainly with neutral atoms, causing thermal bremsstrahlung radiation.

Electrons are one of the components of atoms, alongside protons and neutrons.

* Electrons, atoms and any other object ( such as a baseball, as described by quantum physics )

Electrons are not always shared equally between two bonding atoms ; one atom might exert more of a force on the electron cloud than the other.

Electrons in covalent bonds are split equally between the atoms involved in the bond.

Electrons normally exist in pairs in specific orbitals in atoms or molecules.

Electrons can be used in these situations, whereas X-rays cannot, because electrons interact more strongly with atoms than X-rays do.

Electrons do not penetrate as deeply into matter as X-rays, hence electron diffraction reveals structure near the surface ; neutrons do penetrate easily and have an advantage that they possess an intrinsic magnetic moment that causes them to interact differently with atoms having different alignments of their magnetic moments.

# Electrons ( negatively charged ) are knocked loose from their atoms, causing an electric potential difference.

Electrons that belong to different molecules start " fleeing " and avoiding each other at the short intermolecular distances, which is frequently described as formation of " instantaneous dipoles " that attract each other.

Electrons can also be emitted from the electrodes of certain metals when light of frequency greater than the threshold frequency falls on it.

Electrons can absorb energy from photons when irradiated, but they usually follow an " all or nothing " principle.

Electrons can only exist in certain energy levels.

Electrons at these states can be easily excited to the conduction band, becoming free electrons, at room temperature.

Electrons can also be completely removed from a chemical species such as an atom, molecule, or ion.

Electrons can take on any energy within an unfilled band.

Electrons can gain enough energy to jump to the conduction band by absorbing either a phonon ( heat ) or a photon ( light ).

Electrons can be exchanged between materials on contact ; materials with weakly bound electrons tend to lose them, while materials with sparsely filled outer shells tend to gain them.

* Electrons are fermions, but when they pair up into Cooper pairs they act as bosons, and so can collectively form a coherent state at low temperatures.

Electrons are fermions, and obey the exclusion principle, which means that no two electrons can share a single energy state within an atom ( if spin is ignored ).

Electrons can only reach ( and " illuminate ") a given plate element if both the grid and the plate are at a positive potential with respect to the cathode.

Electrons can move quite freely between energy levels without a high energy cost.

Electrons can transfer from one band to the other by means of carrier generation and recombination processes.

Electrons, within an electron shell around an atom, tend to distribute themselves as far apart from each other, within the given shell, as they can ( due to each one being negatively charged ).

Electrons released on impact escape to the layer of TiO < sub > 2 </ sub > and from there diffuse, through the electrolyte, as the dye can be tuned to the visible spectrum much higher power can be produced.

Electrons in the conduction band can respond to the electric field in the detector, and therefore move to the positive contact that is creating the electrical field.

Electrons also have a long ballistic length at this temperature ; their mean free path can be several micrometres.

Electrons move according to the cross product of the magnetic field and the electron propagation vector, such that, in an infinite uniform field moving electrons take a circular motion at a constant radius dependent upon electron velocity and field strength according to the following equation, which can be derived from circular motion:

Electrons occupying a HOMO of a sigma bond can get excited to the LUMO of that bond.

Electrons and positrons can be discriminated from other charged particles using the emission of transition radiation, X-rays emitted when the particles cross many layers of thin materials.

Electrons in solids have a chemical potential, defined the same way as the chemical potential of a chemical species: The change in free energy when electrons are added or removed from the system.

Electrons in an s orbital benefit from closer proximity to the positively charged atom nucleus, and are therefore lower in energy.

Electrons behave as beams of energy, and in the presence of a potential U ( z ), assuming 1-dimensional case, the energy levels ψ < sub > n </ sub >( z ) of the electrons are given by solutions to Schrödinger ’ s equation,

Electrons ejected from a solid will generally undergo multiple scattering events and lose energy in the form of collective electron density oscillations called plasmons.

Electrons in the closer orbitals experience greater forces of electrostatic attraction ; thus, their removal requires increasingly more energy.

Electrons are accelerated to high speeds in several stages to achieve a final energy that is typically in the GeV range.

Electrons are accelerated to high speeds in several stages to achieve a final energy that is typically in the gigaelectronvolt range.

Electrons exist in energy levels within an atom.

Electrons traversing the periodic magnet structure are forced to undergo oscillations and thus to radiate energy.

Electrons emitted from the cathode possess very low energy of only a few eV.

They ’ ll carry it with them in their future life …. And this future life in the body of eons will be very long, almost as long as the Universe itself .” Suggests Charon, “ the electrons which form my body are not only carriers of what I call ‘ my ’ spirit, but, in fact constitute my spirit itself .” Electrons are sent individually into the Universe to learn and to increase the order of the Universe ; “ the psychic level of the whole Universe progressively elevates itself … during the ‘ successively lived experiences ’ of elemental matter .” The goal of each electron is to increase its energy to the highest level of sustainable excitement ; that is, to contain the most information within the largest stable system of organization possible.

Electrons appear as a track in the inner detector and deposit all their energy in the electromagnetic calorimeter.
