  2. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons [2] (e.g. K + (potassium ion)) while an anion is a negatively charged ion with more electrons than protons. [3] (e.g. Cl-(chloride ion) and OH-(hydroxide ion)).

  3. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    The charge of the resulting ions is a major factor in the strength of ionic bonding, e.g. a salt C + A − is held together by electrostatic forces roughly four times weaker than C 2+ A 2− according to Coulomb's law, where C and A represent a generic cation and anion respectively. The sizes of the ions and the particular packing of the ...

  4. Charged particle - Wikipedia

    en.wikipedia.org/wiki/Charged_particle

    In physics, a charged particle is a particle with an electric charge. For example, some elementary particles, like the electron or quarks are charged. [1] Some composite particles like protons are charged particles. An ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons are also charged particles.

  5. Salt (chemistry) - Wikipedia

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

    In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.

  6. Ionization - Wikipedia

    en.wikipedia.org/wiki/Ionization

    Ionization (or ionisation specifically in Britain, Ireland, Australia and New Zealand) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion.

  7. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions .

  8. Charge carrier - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier

    Proton conductors are electrolytic conductors employing positive hydrogen ions as carriers. [8] In a plasma, an electrically charged gas which is found in electric arcs through air, neon signs, and the sun and stars, the electrons and cations of ionized gas act as charge carriers. [9] In a vacuum, free electrons

  9. Counterion - Wikipedia

    en.wikipedia.org/wiki/Counterion

    In table salt (NaCl, also known as sodium chloride) the sodium ion (positively charged) is the counterion for the chloride ion (negatively charged) and vice versa. A counterion will be more commonly referred to as an anion or a cation, depending on whether it is negatively or positively charged. Thus, the counterion to an anion will be a cation ...
