• Fluorine - Wikipedia

    en.wikipedia.org/wiki/Fluorine Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions.As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.. Among the elements, fluorine ranks 24th in universal abundance and 13th in ...

    www.rsc.org/periodic-table/element/9/fluorine Fluorine's special status also stems from the 'fluorine factor', the ability of this little atom to fine-tune the chemical properties of an entire molecule. For example, replacing hydrogen with fluorine can protect drugs from degradation by metabolic enzymes, extending their active lifetimes inside the body.
  • Fluorine | F2 - PubChem

    pubchem.ncbi.nlm.nih.gov/compound/fluorine Fluorine is a naturally-occurring, pale yellow-green gas with a sharp odor. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids. Sodium fluoride dissolves easily in water, but calcium fluoride does not. Fluorine also combines with hydrogen to make hydrogen fluoride, a colorless gas.

    www.britannica.com/science/fluorine/Production-and-use Fluorine - Fluorine - Production and use: Fluorspar is the most important source of fluorine. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. During the distillation calcium sulfate (CaSO4) is formed, which is insoluble in HF. The hydrogen fluoride is obtained in a fairly anhydrous state by ...
