The other chlorine isotopes are all radioactive, with half-lives too short to occur in nature primordially. Of these, the most commonly used in the laboratory are 36 Cl ( t1/2 = 3.0×10 5 y) and 38 Cl ( t1/2 = 37.2 min), which may be produced from the neutron activation of natural chlorine. See more Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate … See more Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate … See more Chlorine is intermediate in reactivity between fluorine and bromine, and is one of the most reactive elements. Chlorine is a weaker oxidising agent than fluorine but a stronger one than … See more Sodium chloride is the most common chlorine compound, and is the main source of chlorine for the demand by the chemical industry. About 15000 chlorine-containing … See more The most common compound of chlorine, sodium chloride, has been known since ancient times; archaeologists have found evidence that See more Chlorine is too reactive to occur as the free element in nature but is very abundant in the form of its chloride salts.
