I am a dental hygienist and when I was in school we referred the chemical symbol for fluoride as fl2.  I thought it was because the fluoride ion was unstable by itself is this true and if not where could I have gotten this from?  There are others out there that record fluoride as fl2 also.

Fluorine: F or F2 - F as it is a chemical symbol, F2 as fluorine is diatomic gas.

Fluroide is a salt of hydrofluoric acid HF, so formula will depend on the cation - for example NaF is sodium fluoride.

No idea what fl2 is about.

No, it is not true. Fluoride ion, F- was stable in solution. Fluorine atom, F was unstable because it is strongly active.

Further explanation came from Borek!
