The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons ( except in the case of hydrogen-1, which is the only stable nuclide with no neutrons ).

An atom containing an equal number of protons and electrons is electrically neutral, otherwise it has a positive charge if there are fewer electrons ( electron deficiency ) or negative charge if there are more electrons ( electron excess ).

Although particles and their antiparticles have opposite charges, electrically neutral particles need not be identical to their antiparticles.

While protons and neutrons combined to form the first atomic nuclei only a few minutes after the Big Bang, it would take thousands of years for electrons to combine with them and create electrically neutral atoms.

Molecules are typically a set of atoms bound together by covalent bonds, such that the structure is electrically neutral and all valence electrons are paired with other electrons either in bonds or in lone pairs.

Thus, molecules exist as electrically neutral units, unlike ions.

The nucleophile may be electrically neutral or negatively charged, whereas the substrate is typically neutral or positively charged.

In an electrically neutral atom, the number of electrons is equal to the number of protons ( which are positively charged ), resulting in a net zero overall charge

During the formation of macroscopic objects, usually the constituent atoms and ions will combine in such a manner that they form structures composed of neutral ionic compounds electrically bound to neutral atoms.

: APS third rail: The ground-level power supply system known as APS or Alimentation par le sol uses a third rail placed between the running rails, divided electrically into eight-metre segments with three metre neutral sections between.

Unlike the electrically neutral photon of quantum electrodynamics ( QED ), gluons themselves carry color charge and therefore participate in the strong interaction in addition to mediating it, making QCD significantly harder to analyze than QED.

The electrically neutral atom contains a single positively-charged proton and a single negatively-charged electron bound to the nucleus by the Coulomb force.

In any salt, the proportions of the ions are such that the electric charges cancel out, so that the bulk compound is electrically neutral.

In a plasma, the negative free electrons and the positive ions are attracted to each other by the electrostatic force, but they are too energetic to stay fixed together in an electrically neutral molecule.

A molecule () is an electrically neutral group of two or more atoms held together by covalent chemical bonds.

A neutrino (; ) is an electrically neutral, weakly interacting elementary subatomic particle with half-integer spin.

The word " neutron " comes from the fact that it is electrically " neutral ".

Monatomic oxygen is electrically neutral and although it does recombine during the channeling, it does so at a slower rate than the positively or negatively charged free radicals, which attract one another.

An electrically neutral atom contains bound electrons equal in number to the protons in the nucleus.

They are composed of cations ( positively charged ions ) and anions ( negative ions ) so that the product is electrically neutral ( without a net charge ).

It was known that the nucleus was composed of protons and neutrons and that protons possessed positive electric charge while neutrons were electrically neutral.

Even an electrically neutral tachyon would be expected to lose energy via gravitational Cherenkov radiation, because it has a gravitational mass, and therefore increase in speed as it travels, as described above.

These neutrons, being electrically neutral, are no longer held in the stream of plasma by the toroidal magnets and continue until stopped by the inside wall of the tokamak.

Suppose the muon happens to have fallen into an orbit around a deuteron initially, which it has about a 50 % chance of doing if there are approximately equal numbers of deuterons and tritons present, forming an electrically neutral muonic deuterium atom ( d-μ )< sup > 0 </ sup > that acts somewhat like a " fat, heavy neutron " due both to its relatively small size ( again, about 207 times smaller than an electrically neutral electronic deuterium atom ( d-e )< sup > 0 </ sup >) and to the very effective " shielding " by the muon of the positive charge of the proton in the deuteron.

To circumvent the latter issue, experiments has shown that fullerenes could be a good candidate for use instead of sulfur because of the large conjugated π-system that can electrically contact many more atoms at once than a single atom of sulfur.

For example, chemists often choose to look at a small space surrounding the nucleus of an atom: When an electrically neutral atom bonds chemically to another neutral atom that is more electronegative, its electrons are partially drawn away.

In chemistry, a carbyne is a monovalent carbon radical species consisting of an electrically neutral univalent carbon atom with three non-bonded electrons.

The atom is electrically neutral, since both electrons and antiprotons have a charge of-1, whereas helium nuclei have a charge of + 2.

In the ion source, the sample is vaporized ( turned into gas ) and ionized ( transformed into electrically charged particles ) into sodium ( Na < sup >+</ sup >) and chloride ( Cl < sup >-</ sup >) ions.

Using a tunnel junction ( n < sup >+</ sup > p < sup >+</ sup >), an electrically advantageous n-n < sup >+</ sup > p < sup >+</ sup >- p-i-n configuration can be built that also may beneficially influence other structural elements ( e. g. in the form of a Buried Tunnel Junction ( BTJ )).

The idea of conduction-band referencing, and the associated parameters ζ < sub > 0 </ sub > and ζ, are useful when concentrating on the properties of electrons in a metal body that is electrically neutral, is electrically isolated from the rest of the world, and has no long-range electrical fields inside it.

ζ < sub > 0 </ sub > is the energy level, at zero temperature, at which the body under analysis becomes electrically neutral.

ζ < sub > 0 </ sub > can also be interpreted as the energy ( relative to the base of the conduction band ) of the last electron added before the metal becomes electrically neutral.

American wire gauge ( AWG ), also known as the Brown & Sharpe wire gauge, is a standardized wire gauge system used since 1857 predominantly in the United States and Canada for the diameters of round, solid, nonferrous, electrically conducting wire .< ref >< abbr title =" American Society for Testing And Materials "> ASTM </ abbr > Standard B 258-02, Standard specification for standard nominal diameters and cross-sectional areas of AWG sizes of solid round wires used as electrical conductors, ASTM International, 2002 </ ref > The cross-sectional area of each gauge is an important factor for determining its current-carrying capacity.

Widespread adoption of electrochromic windows could save billions of dollars per year in air conditioning costs .< ref > Finally, Phillips has commercialized a mobile phone with an electrically switchable PEDOT mirror.

As blood glucose levels fall below 10 mg / dl ( 0. 55 mM ), most neurons become electrically silent and nonfunctional, resulting in coma.

Because the A-delta fiber is thicker than the C fiber, and is thinly sheathed in an electrically insulating material ( myelin ), it carries its signal faster ( 5 – 30 m / s ) than the unmyelinated C fiber ( 0. 5 – 2 m / s ).

T antennas are typically used at low frequencies where it is not practical to build a quarter-wave vertical antenna because of its height, and the vertical radiating wire is often very electrically short, only a small fraction of a wavelength long, 0. 1λ or less.
