Electrons and have
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 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, being fermions, cannot occupy the same quantum state, so electrons have to " stack " within an atom, i. e. have different spins while at the same place.
Electrons also conduct electric current through conductive solids, and the thermal and electrical conductivities of most metals have about the same ratio.
For instance, " Electrons attract protons " and " Electrons have negative charge " employ the terms " protons " and " negative charge " ( with the latter also implicitly using the concept of " charge ").

Electrons have

Electrons and many elementary particles also have intrinsic magnetic moments, an explanation of which requires a quantum mechanical treatment and relates to the intrinsic angular momentum of the particles as discussed in the article electron magnetic dipole moment.
( Electrons have the Z-value unity, for nuclei it is the atomic number ).
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 have higher diffusion constant than holes leading to fewer excess electrons at the center as compared to holes.
Electrons also have a long ballistic length at this temperature ; their mean free path can be several micrometres.
Electrons that have a velocity component that is parallel to the magnetic field will rather " stretch out " the circle and form helical paths, the pitch of which is subject to the rotation period and the parallel velocity component.

Electrons and mass
Electrons are charged particles ( point charges with rest mass ).

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

Electrons and charged
Electrons in an s orbital benefit from closer proximity to the positively charged atom nucleus, and are therefore lower in energy.
Electrons then leak from the belt to the upper comb and to the terminal, leaving the belt positively charged as it returns down and the terminal negatively charged.
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 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 and leptons

Electrons and .

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