  2. Pauling's principle of electroneutrality - Wikipedia

    en.wikipedia.org/wiki/Pauling's_principle_of...

    There are two possible structures for hydrogen cyanide, HCN and CNH, differing only as to the position of the hydrogen atom. The structure with hydrogen attached to nitrogen, CNH, leads to formal charges of -1 on carbon and +1 on nitrogen, which would be partially compensated for by the electronegativity of nitrogen and Pauling calculated the net charges on H, N and C as -0.79, +0.75 and +0.04 ...

  3. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

  4. Neutral particle - Wikipedia

    en.wikipedia.org/wiki/Neutral_particle

    Other neutral particles are very short-lived and decay before they could be detected even if they were charged. They have been observed only indirectly. They include: Z bosons [PDG 4] Dozens of heavy neutral hadrons: Neutral mesons such as the π 0 [PDG 5] and K 0 [PDG 6] The neutral Delta baryon (Δ 0), [PDG 7] and other neutral baryons, such ...

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  6. Ion-neutral complex - Wikipedia

    en.wikipedia.org/wiki/Ion-neutral_complex

    An ion-neutral complex in chemistry is an aggregate of an ion with one or more neutral molecules in which at least one of the partners has a rotational degree of freedom about an axis perpendicular to the intermolecular direction [1] In chemistry, the dissociation of a molecule into two or more fragments can take place in the gas phase, provided there is sufficient internal energy for the ...

  7. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. [ 16 ] [ 17 ] [ 18 ] A molecule may be homonuclear , that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O 2 ); or it may be heteronuclear , a chemical compound composed of more than one element, as with ...

  8. Electron ionization - Wikipedia

    en.wikipedia.org/wiki/Electron_ionization

    The sample under investigation which contains the neutral molecules is introduced to the ion source in a perpendicular orientation to the electron beam. Close passage of highly energetic electrons in low pressure (ca. 10 −5 to 10 −6 torr) causes large fluctuations in the electric field around the neutral molecules and induces ionization and ...
