Fluorine is a chemical element; it has symbol F and atomic number 9. It is the lightest halogen [ note 1 ] and exists at standard conditions as pale yellow diatomic gas. Fluorine is extremely reactive as it reacts with all other elements except for the light inert gases .
The fluorine–fluorine bond of the difluorine molecule is relatively weak when compared to the bonds of heavier dihalogen molecules. The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8]
Fluoride (/ ˈ f l ʊər aɪ d, ˈ f l ɔːr-/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F − (also written [F] −), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless.
Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O 2 F 2.It can exist as an orange-red colored solid which melts into a red liquid at −163 °C (110 K).
Hydrogen fluoride (fluorane) is an inorganic compound with chemical formula H F. It is a very poisonous, colorless gas or liquid that dissolves in water to yield hydrofluoric acid .
Oxygen fluorides are compounds of elements oxygen and fluorine with the general formula O n F 2, where n = 1 to 6. Many different oxygen fluorides are known: Oxygen monofluoride (OF) Oxygen difluoride (OF 2) Dioxygen difluoride (O 2 F 2) Trioxygen difluoride or ozone difluoride (O 3 F 2) [1] [2] Tetraoxygen difluoride (O 4 F 2) [3] Pentaoxygen ...
Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...
Carbon is stable in a fluorine atmosphere up to about 400 °C, but between 420-600 °C a reaction takes place to give substoichiometric carbon monofluoride, CF 0.68 appearing dark grey. With increasing temperature and fluorine pressure stoichiometries up to CF 1.12 are formed. With increasing fluorine content the colour changes from dark grey ...
