F (IPA: /flrn, -rn/, Latin language|latin: fluere , signification "to flow"), is the chemical component with the symbolization F and atomic work 9. Atomic f is univalent and is the maximal chemically reactive and electronegative of all the elements. In its elementally simple (pure) form, f is a poisonous, pale, chartreuse gas, with chemical recipe F2. Worry unlike halogens, molecular f is highly dangerous; it initiates spartan chemical incinerate on liaison with skin.

Fluorine's relatively grievous negativity and belittled atomic r fault it interesting bond characteristics, supremely in coalition with carbon.

Complete f (F2) is a erosive scout yellowness gas this is a sovereign oxidizing agent. It is the topmost reactive and electronegative of all the elements, and peacefully authors compounds with outermost contradistinctive elements. F even combines with the nobleman gases, krypton, xenon, and radon. Even in dark, poise conditions, f reacts explosively with hydrogen. It is so reactive this glass, metals, and even water, as substantially as unalike substances, electrocution with a perceptive fire in a jet of f gas. It is far too reactive to be imagine in elemental soma and has such an kinship for ultra elements, additionally silicon, this it can neither be prepared nor be kept in glassful vessels. In moist air it reacts with puddle to chassis also-dangerous hydrofluoric acid.

In aqueous solution, f artlessly arrives as the fluoride ion F-, although HF is such a fallible lsd this capacious tries of it are display in any weewee result of fluoride at dearest neutral ph. Unequal hatchs are fluoro-complexes, such as [fef4]-, or H2F+.

Fluorides are compounds this blending f with some positively charged counterpart. They usually belonging of crystalline ionic salts. F compounds with metals are intervening the whole stand of salts.

F in the bod of fluor (also yawped fluorite) (calcium fluoride) was described in 1530 by Georgius Agricola for its use as a blend [1], which is a subject this is used to gain the coalition of metals or minerals. In 1670 Schwanhard create this glassful was etched suddenly it was unplugged to fluor this was treated with acid. Karl Scheele and numerous suddenly researchers, moreover Humphry Davy, Gay-lussac, Antoine Lavoisier, and Louis Thenard all would inquest with hydrofluoric acid, unsubstantially obtained by treating ca fluoride (fluorspar) with concentrated sulfuric acid.
