  2. Fluorine compounds - Wikipedia

    The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8] The covalent radius of fluorine of about 71 picometers found in F 2 molecules is significantly larger than that in other compounds because of this weak ...

    [21] [22] Conversely, bonds to other atoms are very strong because of fluorine's high electronegativity. Unreactive substances like powdered steel, glass fragments, and asbestos fibers react quickly with cold fluorine gas; wood and water spontaneously combust under a fluorine jet. [5] [23]

  4. Intramolecular force - Wikipedia

    en.wikipedia.org/wiki/Intramolecular_force

    The bond length, or the minimum separating distance between two atoms participating in bond formation, is determined by their repulsive and attractive forces along the internuclear direction. [3] As the two atoms get closer and closer, the positively charged nuclei repel, creating a force that attempts to push the atoms apart.

  5. Xenon difluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_difluoride

    Xenon difluoride is a linear molecule with an Xe–F bond length of 197.73 ± 0.15 pm in the vapor stage, and 200 pm in the solid phase. The packing arrangement in solid XeF 2 shows that the fluorine atoms of neighbouring molecules avoid the equatorial region of each XeF

  6. Dioxygen difluoride - Wikipedia

    en.wikipedia.org/wiki/Dioxygen_difluoride

    The O−O bond length is within 2 pm of the 120.7 pm distance for the O=O double bond in the dioxygen molecule, O 2 . Several bonding systems have been proposed to explain this, including an O−O triple bond with O−F single bonds destabilised and lengthened by repulsion between the lone pairs on the fluorine atoms and the π orbitals of the ...

  7. Fluoride - Wikipedia

    en.wikipedia.org/wiki/Fluoride

    Fluoride (/ ˈ f l ʊər aɪ d, ˈ f l ɔːr-/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F − (also written [F] −), whose salts are typically white or colorless.

    Bassetts Ice Cream, a 150-year-old family-run business, has spanned five generations and etched itself into Philadelphia's history as the premier ice cream shop.

  9. Fluorocarbon - Wikipedia

    en.wikipedia.org/wiki/Fluorocarbon

    Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...
