F - Fluorine - periodic table of the elements

The toxic gas, fluorine, is the most reactive element. It was discovered by Karl Scheele in 1771 but not isolated until 1886 when Henri Moissan electrolysed potassium fluoride with some very sophisticated equipment. Curiously, flouride is widely used in toothpaste.
