Fluorine Dating Wiki
Fluorine dating wiki From Wikipedia, the free encyclopedia Fluorine absorption dating is a method used to determine the amount of time an object has been underground. Fluorine absorption dating can be carried out based on the fact that groundwater contains fluoride ions. Items such as bone that are in the soil will absorb fluoride from the groundwater over time.
fluorine dating (uncountable) (archaeology) A technique used to date bones by measuring the amount of fluorine absorbed from the surrounding soil.

Fluorine may interact with biological systems in the form of fluorine-containing compounds. Though elemental fluorine (F 2) is very rare in everyday life, fluorine-containing compounds such as fluorite occur naturally as minerals. Naturally occurring organofluorine compounds are extremely rare. Man-made fluoride compounds are common and are used in medicines, pesticides, and materials.
Dec 11, · Properties []. The properties of fluorine depend very much on which kind of compound it is a part of. Pure fluorine is a greenish-yellow, extremely reactive, toxic gas. Fluorine is incredibly reactive because its electronegativity is highest of all elements: its outermost electron shell has only a single hole in it, and it loves to pull any other electrons it can lay its hands on into said hole.
