{"id":8,"count":5,"description":"The halogens are five non-metallic elements with similar properties, found in group 17 of the periodic table.\r\n\r\nThe halogens are <a href=\"https:\/\/thechemicalelements.com\/fluorine\/\">fluorine<\/a>, <a href=\"https:\/\/thechemicalelements.com\/chlorine\/\">chlorine<\/a>, <a href=\"https:\/\/thechemicalelements.com\/bromine\/\">bromine<\/a>, <a href=\"https:\/\/thechemicalelements.com\/iodine\/\">iodine<\/a>, and <a href=\"https:\/\/thechemicalelements.com\/astatine\/\">astatine<\/a>. Because they are missing an electron from their outermost shell, they react readily with most metals to form salts.\r\n\r\nThe halogens or halogen elements are a group in the periodic table consisting of five chemically related elements, fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).\r\n\r\nThe artificially created element 117 (ununseptium) may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17.\r\n\r\n[table id=5 \/]","link":"https:\/\/thechemicalelements.com\/halogens\/","name":"Halogens","slug":"halogens","taxonomy":"category","parent":0,"meta":[],"_links":{"self":[{"href":"https:\/\/thechemicalelements.com\/wp-json\/wp\/v2\/categories\/8"}],"collection":[{"href":"https:\/\/thechemicalelements.com\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"https:\/\/thechemicalelements.com\/wp-json\/wp\/v2\/taxonomies\/category"}],"wp:post_type":[{"href":"https:\/\/thechemicalelements.com\/wp-json\/wp\/v2\/posts?categories=8"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
