What it is Filled
The chemical element with symbol F and atomic number 9, the lightest halogen and the most electronegative element, whose elemental form under ordinary conditions is an extremely reactive pale yellow diatomic gas, occurring in nature predominantly in compounds such as fluorite and fluor-uvite, although rare natural occurrences of molecular fluorine are known, with one stable isotope fluorine-19 and short-lived radioisotopes such as fluorine-18 used in PET imaging and fluorine-20 to fluorine-24 studied in nuclear physics; fluorine compounds are used in refrigerants, polymers such as PTFE, pharmaceuticals, toothpaste and uranium enrichment.
Why it exists Filled
Let an agent explain fluorine and its properties, relay chemistry, isotopes, occurrence and uses from chemical references, describe safety at the level of public reference sources, and distinguish fluorine from fluoride ions, fluorite and fluorocarbons, without providing hazardous synthesis detail.
Distinguishing features Filled
