Fluorine is a Group 17 element. Fluorine is the most electronegative
and chemically reactive of all elements. It is a pale yellow, corrosive gas, which
reacts with practically all organic and inorganic substances.

Finely divided metals, glass, ceramics, carbon, and even water burn in
fluorine with a bright flame.

Atomic bomb projects and nuclear energy applications after WWII made it
necessary to produce large quantities of fluorine since isotopes of
uranium can be separated through the gas diffusion of UF6.

Compounds of fluorine with noble gases such as xenon, radon,
and krypton are known. Elemental fluorine and the fluoride ion
(in quantity) are highly toxic.
