#Chlorine is a #ChemicalElement with the symbol Cl and #AtomicNumber 17.   The second-lightest of the #Halogens, it appears between #Fluorine and #Bromine in the #PeriodicTable and its properties are mostly intermediate between them.   Chlorine is a yellow-green gas at room temperature. It is an extremely #ReactiveElement and a strong #OxidisingAgent: among the elements, it has the highest #Electron affinity and the third-highest electronegativity on the revised Pauling scale, behind only #Oxygen and fluorine.   Chlorine played an important role in the #Experiments conducted by #Medieval #Alchemists, which commonly involved the heating of chloride salts like #AmmoniumChloride (sal ammoniac) and #SodiumChloride (#CommonSalt), producing various chemical substances containing chlorine such as #HydrogenChloride, #MercuryChloride (corrosive sublimate), and #HydrochloricAcid (in the form of aqua regia).   However, the nature of free #ChlorineGas as a separate substance was only recognised around 1630 by Jan Baptist van Helmont. Carl Wilhelm Scheele wrote a description of chlorine gas in 1774, supposing it to be an oxide of a #NewElement. In 1809, chemists suggested that the gas might be a #PureElement, and this was confirmed by Sir Humphry Davy in 1810, who named it after the Ancient Greek χλωρός (khlōrós, "pale green") because of its colour.  In the upper #Atmosphere, chlorine-containing #OrganicMolecules such as #ChloroFluoroCarbons have been implicated in #Ozone depletion.   Small quantities of elemental chlorine are generated by oxidation of chloride ions in neutrophils as part of an #ImmuneSystem response against bacteria.
