The halogens (/ ˈhælədʒən, ˈheɪ -, - loʊ -, - ˌdʒɛn / [1][2][3]) 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 [4] would exclude tennessine as its chemistry is unknown and i...

Mar 18, 2025 · Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). Learn more about the properties of halogens in this article.

Nov 6, 2019 · The halogens are a group of elements on the periodic table. It is the only element group that includes elements capable of existing in three of the four main states of matter at room temperature: solid, liquid, and gas. The word halogen means "salt-producing," because halogens react with metals to produce many important salts.

Oct 10, 2020 · The halogens are a periodic table group of elements. They are found on the righthand side of the periodic table, just to the left of the noble gas group. The halogens are group VII or 7 in older nomenclature and group 17 in modern IUPAC nomenclature.

Halogens are found in the environment only in the form of ions or compounds because of their high reactivity. We will look at some of the physical and chemical properties of Halogens. Also Read: Halogenation. Molecules of all halogens are homonuclear diatomic. What this means is that their molecules exist with two atoms each.

Jun 30, 2023 · 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).

Jul 30, 2024 · The halogens are highly reactive nonmetallic elements. They commonly form ionic bonds with metals and covalent bonds with other nonmetals. The halogens are the only group of elements that include elements in all of the three main states of matter: gases, liquids, and solids.

Mar 21, 2025 · Pick two elements that are halogens. For each, write the name, chemical symbol, and atomic weight. What does the term “halogen” mean? What is the outer shell electron configuration for the halogens? What is the physical state of each halogen at room temperature? Where are the halogens found?

Definition: What are halogens? Halogens are special category of highly reactive, non-metal elements which fall in group VIIa of the periodic table. Because of their high reactivity, the halogen family do not exist in nature in their native form, i.e. in monoatomic form.

The halogens are the family of chemical elements that includes fluorine (atomic symbol F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The halogens make up Group VIIA of the Periodic Table of the elements.
