WebChemical element, Fluorine, information from authoritative sources. Look up properties, history, uses, and more. Fluorine (9F) has 18 known isotopes ranging from F to F (with the exception of F ) and two isomers ( F and F ). Only fluorine-19 is stable and naturally occurring in more than trace quantities; therefore, fluorine is a monoisotopic and mononuclidic element. The longest-lived radioisotope is F ; it has a half-life of 109.734(8) min. All other fluorine isotopes have half-lives of less than a minute, and most of those less than a second. The least stable kn…
