1 Henri Moissan earned the 1906 Nobel Prize in Chemistry for being the chemist who finally successfully isolated fluorine (and the invention of the electric arc furnace). 2  Fluorine is the 13th most common element in the Earth's crust.

At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. There is therefore a trend in state from gas to liquid to solid down the group.

It is obtained by electrolyzing a solution of potassium hydrogen fluoride in anhydrous hydrogen fluoride in container of transparent fluorspar or metal. Element Classification: Halogen. Isotopes: Fluorine has 17 known isotopes ranging from F-15 to F-31. F-19 is the only stable and most common isotope of fluorine.

Fluorine is added to city water supplies in the proportion of about one part per million to help prevent tooth decay. Sodium fluoride (NaF), stannous(II) fluoride (SnF 2) and sodium monofluorophosphate (Na 2 PO 3 F) are all fluorine compounds added to toothpaste, also to help prevent tooth decay. Hydrofluoric acid (HF) is used to etch glass, including most of the glass used in light bulbs.

Melting point and boiling point. The halogens have low melting points and boiling points. This is a typical property of non-metals. Fluorine has the lowest melting point and boiling point. The melting points and boiling points then increase as you go down the group. Melting and boiling points of Group 7 elements.

Properties: Fluorine has a melting point of -219.62°C (1 atm), boiling point of -188.14°C (1 atm), density of 1.696 g/l (0°C, 1 atm), specific gravity of liquid of 1.108 at its boiling point, and valence of 1. Fluorine is a corrosive pale yellow gas.

Fluorine is pronounced as FLU-eh-reen or as FLU-eh-rin. History and Uses: Fluorine is the most reactive of all elements and no chemical substance is capable of freeing fluorine from any of its compounds. For this reason, fluorine does not occur free in nature and was extremely difficult for scientists to isolate.

Fluorine Trivia: 1  Fluorine in the form of the mineral fluorite was used in the 1500s to aid in ore smelting. 2  Fluorine was suspected to be an element as early as 1810 but wasn't successfully isolated until 1886.
