  2. Ionic conductivity (solid state) - Wikipedia

    en.wikipedia.org/wiki/Ionic_conductivity_(solid...

    Ionic conductivity (denoted by λ) is a measure of a substance's tendency towards ionic conduction. Ionic conduction is the movement of ions. The phenomenon is observed in solids and solutions. Ionic conduction is one mechanism of current. [1]

  3. Salt (chemistry) - Wikipedia

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

    The constituent ions are held together by electrostatic forces termed ionic bonds. The component ions in a salt can be either inorganic, such as chloride (Cl −), or organic, such as acetate (CH 3 COO −). Each ion can be either monatomic (termed simple ion), such as sodium (Na +) and chloride (Cl −) in sodium chloride, or polyatomic, such ...

  4. Molar conductivity - Wikipedia

    en.wikipedia.org/wiki/Molar_conductivity

    For multivalent ions, it is usual to consider the conductivity divided by the equivalent ion concentration in terms of equivalents per litre, where 1 equivalent is the quantity of ions that have the same amount of electric charge as 1 mol of a monovalent ion: ⁠ 1 / 2 ⁠ mol Ca 2+, ⁠ 1 / 2 ⁠ mol SO 2−

  5. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and a positive ion. [ 5 ]

  6. Delocalized electron - Wikipedia

    en.wikipedia.org/wiki/Delocalized_electron

    In chemistry, delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond. [1] The term delocalization is general and can have slightly different meanings in different fields: In organic chemistry, it refers to resonance in conjugated systems and aromatic compounds.

  7. Ionic conductivity - Wikipedia

    en.wikipedia.org/wiki/Ionic_conductivity

    Ionic conductivity may refer to: Conductivity (electrolytic) , electrical conductivity due to an electrolyte separating into ions in solution Ionic conductivity (solid state) , electrical conductivity due to ions moving position in a crystal lattice

  8. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    This means that inside the metal one can generally not distinguish molecules, so that the metallic bonding is neither intra- nor inter-molecular. 'Nonmolecular' would perhaps be a better term. Metallic bonding is mostly non-polar, because even in alloys there is little difference among the electronegativities of the atoms participating in the ...

  9. Electrolyte - Wikipedia

    en.wikipedia.org/wiki/Electrolyte

    An electrolyte is a substance that conducts electricity through the movement of ions, but not through the movement of electrons. [1] [2] [3] This includes most soluble salts, acids, and bases, dissolved in a polar solvent like water.
