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

Electrons emitted from the filament move several times in back and forth movements around the grid before finally entering the grid.

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

Electrons emitted at any point are accelerated a modest distance down the funnel before impacting the surface, perhaps on the opposite side of the funnel.

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 are usually generated in an electron microscope by a process known as thermionic emission from a filament, usually tungsten, in the same manner as a light bulb, or alternatively by field electron emission.

Electrons in the conduction band may move freely throughout the material in the presence of an electrical field.

Electrons that populate a shell are said to be in a bound state.

These he interpreted as " negative-energy electrons " and attempted to identify them with protons in his 1930 paper A Theory of Electrons and Protons However, these " negative-energy electrons " turned out to be positrons, and not protons.

Electrons in this state are 45 % likely to be found within the solid body shown.

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

Electrons that populate a shell are said to be in a bound state.

Electrons will be accelerated in the opposite direction to the electric field by the average electric field at their location.

Electrons in atoms and molecules can change ( make transitions in ) energy levels by emitting or absorbing a photon ( of electromagnetic radiation ) whose energy must be exactly equal to the energy difference between the two levels.

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

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 in non-bonding orbitals tend to be in deep orbitals ( nearly atomic orbitals ) associated almost entirely with one nucleus or the other, and thus they spend equal time between and not between nuclei.

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

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 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 in pi bonds are sometimes referred to as pi electrons.

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 form notional shells around the nucleus.

# Electrons jump between orbitals in a particle-like fashion.

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

Electrons ( the other major component of the atom ) are leptons.

Electrons are the charge carriers in metals and they follow an erratic path, bouncing from atom to atom, but generally drifting in the opposite direction of the electric field.

Electrons were first discovered as the constituents of cathode rays.

Electrons are extracted from metal electrodes either by heating the electrode, causing thermionic emission, or by applying a strong electric field and causing field electron emission.

Electrons which diffuse from the cathode into the P-doped layer, or anode, become what is termed " minority carriers " and tend to recombine there with the majority carriers, which are holes, on a timescale characteristic of the material which is the p-type minority carrier lifetime.

Electrons are responsible for emission of most EMR because they have low mass, and therefore are easily accelerated by a variety of mechanisms.

Electrons are at the heart of cathode ray tubes, which have been used extensively as display devices in laboratory instruments, computer monitors and television sets.

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

: Electrons are transferred from iron reducing oxygen in the atmosphere into water on the cathode, which is placed in another region of the metal.

Electrons flow in the external circuit.

Electrons flow from the source terminal towards the drain terminal if influenced by an applied voltage.

Electrons are drawn from the anode to the cathode through an external circuit, producing direct current electricity.

His most noted publication was the famous 1919 article " The Arrangement of Electrons in Atoms and Molecules " in which, building on Gilbert N. Lewis's cubical atom theory and Walther Kossel's chemical bonding theory, he outlined his " concentric theory of atomic structure ".

Electrons are particulate radiation and, hence, have cross section many times larger than photons, so that they do not penetrate the product beyond a few inches, depending on product density.

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 and how they interact with electromagnetic fields are important in our understanding of chemistry and physics.
