Fluoride (F-) is a naturally occurring variation of fluorine (the 13th most common element in the Earth's crust), and present in low concentrations of most fresh and saltwater sources. Its natural atomic state allows it to easily bond with other chemicals in order to act as a base for other compounds, thus making it (fluorite, fluorine, etc..) invaluable at various levels of manufacturing.
