definition

The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity.

Alloys of magnesium and other metals, like aluminum or zinc, that were manufactured by the German company Chemische Fabrik Griesheim-Elektron.

Electric charge consists, therefore, in an excess or deficit of negative electrons in a body.

An electric current consists of a moving stream of electrons.

The released electrons move round in the external part of the circuit to produce the negative charge on the cathode electrode.

Measurements of such order are usually made by diffraction techniques, which detect the ionic cores and the spins of the conduction electrons.

All of these particular cases contain a very electronegative element with an active lone pair of electrons - either oxygen or nitrogen.

Homolytic bond fission means the original pair of (Cl-Cl) bonding electrons is split between the two radicals formed.

The substances that can exist with missing electrons are called free radicals.

This in turn was expected to attract electrons, making the quark glob metallic and opaque.

This light signal is converted to electrons which are subsequently amplified before being used to modulate the intensity of a cathode ray tube display.

Even more complicated integrated atom optics devices and networks, similar to integrated circuits for electrons, can be devised.

Using the equation l p = h. If the momentum of the electrons is zero, then the wavelength they have is infinite.

The center of the anode has become perforated due to bombardment by electrons.

When the electrons strike the phosphor dots they glow to give the colors.

Bombardment with x-ray photons leads to the emission of electrons, these are called photoelectrons.

The conversion of electron energy into X-ray photons is also more efficient with fast rather than slow electrons.

Furthermore, polarized electrons have been used to make polarized photons in the dilute magnet materials.

We can consequently treat rationality as a theoretical posit, much like electrons, viruses and the other theoretical posits of science.

For purposes of theoretical discussions relating to moving radiators and reflectors, it is important to remember that the dynamics of all this theory of electrons involves the neglect of terms of the order (v/c) 2, not merely in the value of K but throughout.

Lorentz, and leave no manner of doubt that the radiating centres are negative electrons.

The fact that in certain simple cases where a line when looked at equatorially splits into a triplet, the ratio of the charge to the mass is found by Lorentz's theory to be equal to that observed in the carrier of the kathode ray, shows that in these cases the electron moves as an independent body and is not linked in its motion to other electrons.

For example, from the evidence of molar changes due to the obvious parts of bodies, science first comes to believe in molecular changes due to imperceptible particles, and then tries to conceive the ideas of particles, molecules, atoms, electrons.

In every solid body there is a continual atomic dissociation, the result of which is that mixed up with the atoms of chemical matter composing them we have a greater or less percentage of free electrons.

In addition, the RC I provided electrons to soluble electron acceptors (ferredoxin) for use in organic synthesis.

You can see the cathode electrode in the foreground streaming electrons to the grid or slice plate and then onto the aluminum anode plate.

In modulation doping, facing layers of gallium arsenide and aluminum gallium arsenide squeeze electrons into an essentially two-dimensional electron gas, or 2DEG.

The typical helium atom consists of a nucleus of two protons and two neutrons surrounded by two electrons.

At apogee, the craft will be above it, seeing upgoing ions in the bright Aurora and upgoing electrons in the black aurora.

Aliphatic any non-aromatic organic compound Aromatic any organic compound containing de-localised electrons in a ring structure - e.g. benzene, benzoic acid.

Germanium-76 can undergo double beta decay in which two neutrons decay into protons, electrons and antineutrinos.

In the last lesson we saw that atoms can lose or gain electrons to form ionic bonds.

With the new cold cathode carbon nanotube source, the electrons bunches are instantaneously created at the source.

In the Coolidge tube, the bulb could be completely evacuated and electrons were liberated from a heated spiral cathode.

By measuring the curvature of the tracks, the energy of the electrons to be estimated.

A beam of X-rays is diffracted by the electrons in a crystalline material, just as visible light is diffracted by larger objects.

Sodium in a sodium lamp a stream of electrons is passed between tungsten electrodes in a tube containing sodium vapor.

The hydrogen atoms aren't involved in any way with the delocalised electrons.

It is associated with relativistic electrons or cosmic ray electrons, so named because they travel at speeds comparable with that of light.

Elements from group 3 across to the noble gases all have their outer electrons in p orbitals.

Notice that the 2p electrons are all lumped together whereas the 3p ones are shown in full.

Interactive Flash Tutorial Photomultiplier Tubes Discover how photomultipliers work by amplifying the electrons generated by a photocathode exposed to a photon flux.

The process, called inverse electron spin resonance, uses the magnetic field to deflect electrons and to modify their magnetic direction.

Electric current can also be described as the flow of microscopic particles called electrons flowing through wires and electronic components and appliances.

Also describes a chemical reaction in which one or more electrons are added to an atom or molecule.

Free radicals are molecules that steal electrons from other molecules, turning the other molecules into free radicals and destabilizing the molecules in the body's cells.

Coenzyme Q10 is a natural substance produced by the body that transports electrons during cellular respiration, or the process in which cells get their energy from oxygen.

Air ionizers use electricity to discharge electrons into the air which attach themselves to positively-charged particles like dust, pollen and other pollutants.
