History
The atomic number is 9 and the chemical symbol is F. The name derives from the Latin fluere for flow or flux since fluorspar (CaF2) was used as a flux in metallurgy because of its low melting point. It was discovered in hydrofluoric acid by the Swedish pharmacist and chemist Carl-Wilhelm Scheele in 1771 but it was not isolated until 1886 by the French pharmacist and chemist Ferdinand-Frederic-Henri Moisson.Holden, Norman E., (2004).
