  2. Caesium fluoride - Wikipedia

    en.wikipedia.org/wiki/Caesium_fluoride

    Caesium fluoride has the halite structure, which means that the Cs + and F − pack in a cubic closest packed array as do Na + and Cl − in sodium chloride. [3] Unlike sodium chloride, caesium fluoride's anion is smaller than its cation, so it is the anion size that sterically inhibits larger coordination numbers than six under normally ...

  3. Oxygen - Wikipedia

    en.wikipedia.org/wiki/Oxygen

    The name oxygen was coined in 1777 by Antoine Lavoisier, who first recognized oxygen as a chemical element and correctly characterized the role it plays in combustion. Common industrial uses of oxygen include production of steel , plastics and textiles , brazing, welding and cutting of steels and other metals , rocket propellant , oxygen ...

  4. Configuration state function - Wikipedia

    en.wikipedia.org/wiki/Configuration_state_function

    In quantum chemistry, a configuration state function (CSF), is a symmetry-adapted linear combination of Slater determinants. A CSF must not be confused with a configuration. In general, one configuration gives rise to several CSFs; all have the same total quantum numbers for spin and spatial parts but differ in their intermediate couplings.

  5. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    A pure substance is composed of only one type of isomer of a molecule (all have the same geometrical structure). Structural isomers have the same chemical formula but different physical arrangements, often forming alternate molecular geometries with very different properties. The atoms are not bonded (connected) together in the same orders.

  6. Oxygen difluoride - Wikipedia

    en.wikipedia.org/wiki/Oxygen_difluoride

    Oxygen difluoride is a chemical compound with the formula OF 2. As predicted by VSEPR theory, the molecule adopts a bent molecular geometry. [citation needed] It is a strong oxidizer and has attracted attention in rocketry for this reason. [5] With a boiling point of −144.75 °C, OF 2 is the most volatile (isolable) triatomic compound. [6]

  7. Caesium - Wikipedia

    en.wikipedia.org/wiki/Caesium

    Caesium fluoride (CsF) is a hygroscopic white solid that is widely used in organofluorine chemistry as a source of fluoride anions. [39] Caesium fluoride has the halite structure, which means that the Cs + and F − pack in a cubic closest packed array as do Na + and Cl − in sodium chloride . [ 28 ]

  8. Bent molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Bent_molecular_geometry

    In chemistry, molecules with a non-collinear arrangement of two adjacent bonds have bent molecular geometry, also known as angular or V-shaped. Certain atoms, such as oxygen, will almost always set their two (or more) covalent bonds in non-collinear directions due to their electron configuration.

  9. Solid oxygen - Wikipedia

    en.wikipedia.org/wiki/Solid_oxygen

    Solid oxygen O 2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum. Oxygen molecules have attracted attention because of the relationship between the molecular magnetization and crystal structures, electronic structures, and superconductivity.
