How is fluorine purified?

Answer 1

Fluorine (IPA: /ˈflʊərɪːn, -ɔːrɪːn/, from Latin fluere, meaning "to flow"), is the chemical element with the symbol F and atomic number 9. Atomic fluorine is univalent and is the most chemically reactive and electronegative of all the elements. In its elementally isolated (pure) form, fluorine is a poisonous, pale, yellow-green gas, with chemical formula F2. Like other halogens, molecular fluorine is highly dangerous; it causes severe chemical burns on contact with skin.

Fluorine's relatively large electronegativity and small atomic radius give it interesting bonding characteristics, particularly in conjunction with carbon.
