  2. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  3. Sodium chloride - Wikipedia

    en.wikipedia.org/wiki/Sodium_chloride

    Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .

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

    X-ray spectrometer developed by W. H. Bragg. In 1913 the structure of sodium chloride was determined by William Henry Bragg and William Lawrence Bragg. [2] [3] [4] This revealed that there were six equidistant nearest-neighbours for each atom, demonstrating that the constituents were not arranged in molecules or finite aggregates, but instead as a network with long-range crystalline order. [4]

  5. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    A Lewis acid (named for the American physical chemist Gilbert N. Lewis) is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct.

    en.wikipedia.org/wiki/File:NaCl_bonds.svg

    English: The crystal structure of sodium chloride, NaCl, a typical ionic compound. The __ purple spheres represent sodium cations, Na +, and the __ green spheres represent chloride anions, Cl −. The yellow stipples represent the electrostatic force in each ionic bond.

  7. Rubidium chloride - Wikipedia

    en.wikipedia.org/wiki/Rubidium_chloride

    At high temperature and pressure, RbCl adopts the caesium chloride (CsCl) structure (NaCl and KCl undergo the same structural change at high pressures). Here, the chloride ions form a simple cubic arrangement with chloride anions occupying the vertices of a cube surrounding a central Rb +.

  8. Crystal structure - Wikipedia

    en.wikipedia.org/wiki/Crystal_structure

    Crystal structure of table salt (sodium in purple, chlorine in green). In crystallography, crystal structure is a description of ordered arrangement of atoms, ions, or molecules in a crystalline material. [1]

    Note: ρ is density, n is refractive index at 589 nm, [clarification needed] and η is viscosity, all at 20 °C; T eq is the equilibrium temperature between two phases: ice/liquid solution for T eq < 0–0.1 °C and NaCl/liquid solution for T eq above 0.1 °C.
