Fluorine: is a chemical element with symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

Organic fluorides have very high chemical and thermal stability; their major uses are as refrigerants, electrical insulation and cookware, the such as PTFE (Teflon). Some prescription drugs such as atorvastatin and fluoxetine contain fluorine, and fluoride is also used to inhibit dental cavities. You can commonly find fluoride in toothpaste and water that’s fluoridated.

Organofluorines, organic members of the fluorine family, exhibit biopersistence meaning that they are last for extended periods of time. Perfluoroalkyl acids (PFAAs), are noted persistent organic pollutants PFAAs have been found in trace quantities worldwide from polar bears to humans, with PFOS and PFOA known to reside in breast milk and the blood of newborn babies.
