Overview

Fluorine is a pale yellow, highly reactive gas that forms strong bonds and reacts with nearly all other elements.

Properties

It is the most electronegative element, extremely corrosive and forms stable fluoride compounds.

Occurrence and Uses

Found in minerals like fluorite, fluorine is used in refrigerants, pharmaceuticals, fluoropolymers and water fluoridation compounds.

Isotopes and Safety

Stable F 19 is the only stable isotope; elemental fluorine is highly toxic and corrosive and requires specialized containment and neutralization.
