Background Information

Fluorine was discovered by André-Marie Ampére in 1810 and named by Humphry Davy after the mineral fluorite. Fluorine is extremely reactive and poisonous but is the lightest halogen and most electronegative element. It exists as a pale yellow gas in standard conditions.

How is it used in everyday life?

Fluorine is commonly used in dental hygiene such as toothpaste but is also used in pharmaceuticals such as antidepressants and steroids. Fluorine can also be used in PET scanning, giving a high quality image of the organs within the body. Finally, this chemical can be used as an agrochemical for farming, primarily used to kill weeds and fungus.
