WebFluorine (from L. fluere, meaning “to flow”), is the chemical element in the periodic table that has the symbol F and atomic number 9. Atomic fluorine is univalent and is the most chemically reactive and electronegative of all the elements. In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F 2. WebThere are tests to identify Fluoride (F -) anion in qualitative analysis. Fluoride ion forms aqueous solutions with some metal cations and sometimes forms precipitates with some cations.
