7 Interesting Facts Of Fluorine
What is Fluorine?
• Fluorine is a chemical element, with symbol F and has an atomic
• It is the lightest halogen and exists as an exceedingly hazardous
light yellow diatomic gas at normal conditions.
• As the most electronegative component, it is reactive in nature.
• Every other component, including some noble gasses forms
compounds with fluorine.
• Fluorine reacts to all other elements and no chemical substance
can liberate fluorine from any of its compounds. Hence, fluorine
does not exist free in nature and was difficult for scientists to
• It exits in volcanic gasses and warm waters. Its main source is
fluorite; however, it also occurs in cryolite, seawater, bones and
teeth. Fluorine is produced by electrolysis under unique conditions.
How did fluorine get its name?
• Fluorine is derived from the Latin word "Fluere" which
signifies "Stream" or "Flux".
• Fluorine as calcium fluoride, or fluorite, was utilized as a
flux in mineral refining.
• Natural fluorine is a light yellow gas that is dangerous,
destructive and reactive.
• It is the most electronegative of all the elements and
responds with about all natural and inorganic
substances, including metal, glass, pottery and water.
• Generally fluorine forms compounds with the non-
responsive noble gasses, including xenon, radon and
What are some Characteristics of fluorine (F) that
distinguish from other elements?
• Electron Configuration: Fluorine molecules have nine electrons,
one less than neon, and electron configuration of 1s22s22p5: two
electrons in a filled inward shell and seven in outer shell requiring
one more to be filled. The external electrons are incapable at
atomic protecting, and experience a high effective atomic charge
of 9-2 = 7; this influences the atom’s physical property.
• Reactivity: Reactions of basic fluorine with metals require different
conditions. Alkali metals cause blasts and alkaline metals are
dynamic; to keep passivation from the formation of metal fluoride
layers, other metals such as aluminium and iron must be
• Isotopes: Only one isotope of fluorine occurs normally in large
quantity, the steady isotope 19
F. It has a high magnetogyric
proportion and is sensible to magnetic fields; since it is likewise
the main stable isotope, it is utilized as magnetic resonance
What are some uses of fluorine (F)?
• Fluorine is a gas under normal temperatures and pressures.
• It is normally shipped as a compressed gas in cylinders or
generated by electrolysis of hydrogen fluoride or by recycling
chemical products containing fluoride.
• Hydrofluoric corrosive (HF) is utilized to cut glass, including the
greater part of the glass used in manufacturing bulbs.
• Fluorine joins with carbon to shape a class of compounds known as
• Few of these compounds, for example: dichlorodifluoromethane
(CF2Cl2) were broadly utilized as a part of aerating and AC’s and
refrigerating system and in vaporized spray cans. Today, fluorine is
still produced through the electrolysis of potassium fluoride
and hydrofluoric acid and through the electrolysis of liquid potassium
acid fluoride (KHF2).
Medical implication of fluorine (F)
• Studies from the mid-twentieth century onwards indicate topical
fluoride lessens dental caries.
• This was first ascribed to the transformation of tooth enamel
hydroxyapatite into the stronger fluorapatite, yet thinks about on pre-
fluoridated teeth discredited this hypothesis.
• Reviews of the scholarly literature in 2000 and 2007 related water
fluoridation with a critical decrease of tooth decay in youngsters.
• 20 per cent of present day pharmaceuticals contain fluorine.
• The major part of inhaled sedatives is intensely fluorinated; the
model halothane is considerably more idle and powerful than its
Where is fluorine found in the Environment?
• Presence of fluorine in natural water is controlled by
weathering of rocks.
• Weathering is a complete process involving
adsorption-desorption and dissolution precipitation
• During weathering the circulation of water in rocks
and soils, fluorine also be dissolve in ground water.
• Fluorine in apatite is very stable while the fluorine
from mica is drained out quickly.
• The occurrence of fluorine in ground water varies
depending upon the type of the rocks from which it
Interesting facts about fluorine (F)
• Fluorine is the most receptive and most electronegative of all
the chemical elements. The elements with which it doesn't
respond are oxygen, helium, neon, and argon. Fluorine is the
only element which will shape compounds with noble gasses
xenon, krypton, and radon.
• Fluorine is the thirteenth most abundant component in the
Earth's crust. It is reactive to the point that it is not discovered
normally in natural form, but rather just in mixes. Fluorine is
found in minerals, including fluorite, topaz, and feldspar.
• It is reactive in nature, storing fluorine is tough. Hydrofluoric
acid (HF), for instance, is so destructive it will break up glass.
All things being equal, HF is more secure and is easier to
transport and handle than pure fluorine.
• There is just a single stable isotope of fluorine, F-19.
