Halogen 卤素

Image: Liquid fluorine at cryogenic temperatures
Image: Liquid bromine
Image: Iodine crystal
From left to right: chlorine, bromine, and iodine at room temperature. Chlorine is a gas, bromine is a liquid, and iodine is a solid. Fluorine could not be included in the image due to its high reactivity, and astatine due to its radioactivity.

The halogens or halogen elements (/ˈhæləən, ˈh-, -l-, -ˌɛn/) are a group in the periodic table consisting of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The artificially created element 117 (ununseptium) may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17.
