Fluorine


The fluorine compounds are very common and well known for a long time, but it was only in 1886 that a method was discovered to remove electrons to fluorine ions in order to produce elemental fluorine. In 1860, Gore was able to produce small amounts of fluorine gas, but with a very arcaic method. It was Henri Moissan, in 1886, the first to isolate the element by electrolysis of a mixture of fluoridric acid with potassium fluoride and hydrogen. The name fluorine derives from the latim fluo (that runs), because of the use of calcium fluoride as dissolvent.
