May 28, 2024 · Halogen is a group of six nonmetallic elements that produce salts with sodium and are strong oxidizing agents. Learn about their chemical behaviour, compounds, examples, and applications in this article from Britannica.
The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n /) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors would exclude tennessine as its chemistry ...
Learn about halogens, the nonmetals in Group 17 of the periodic table, with high reactivity and diverse forms. Find out their physical and chemical properties, types of compounds, and applications in various fields.
Oct 10, 2020 · Learn about the six halogen elements: fluorine, chlorine, bromine, iodine, astatine, and tennessine. Find out their properties, uses, and biological role in this article.
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Nov 6, 2019 · Properties of the Halogens . These reactive nonmetals have seven valence electrons. As a group, halogens exhibit highly variable physical properties. Halogens range from solid (I 2) to liquid (Br 2) to gaseous (F 2 and Cl 2) at room temperature.
The elements of Group VIIA (new Group 17 - fluorine, chlorine, bromine, iodine, and astatine) are called the halogens (yellow column). The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts.
