- The halogens or halogen elements (/ˈhaelɵdʒɨn/) ˈhælɵdʒɨn 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. halogenn the modern IUPAC nomenclature, this group is known as group 17. The name 'halogen' means 'salt-producing'. When halogens react with metals they produce a wide range of salts, including calcium fluoride, sodium chloride (common salt), silver bromide and potassium iodide.

What is the difference between a halogen and a halide? A halogen is a representative element from group VII in the periodic table. More specifically, Fluorine, Chlorine, Bromine, Iodine, and Astatine.

Halide See also: Organic halide. A halide is a binary compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically ununseptide compound.

BROMINE Halogens are the elements that make up Group 17 (VIIA) of the periodic table. The periodic table is a chart that shows how elements are related to one another. The halogens are also known as the salt formers. Fluorine, chlorine, bromine, iodine, and astatine form salts when chemically combined with a metal.

Alkali Metals and Halogens Alkali Metals and Halogens. Alkali metals and halogens are the chemical elements which are members of the group 1 and group 17 in the periodic table. They are called as s-block elements and p-block elements respectively. Alkali metals have the differentiating electron which enters the s-orbital of the valence shell.

Elements for Kids Elements for Kids. Halogens. The halogens are a group of elements in the periodic table. They are located to the right of the other nonmetals and to the left of the noble gases. Elements in the halogen group have seven electrons in their outer shells giving them many unique properties. What elements are halogens? The halogens include the five elements fluorine, chlorine, bromine, iodine, and astatine. They make up column 17 of the periodic table. What are the similar properties of halogens?

- The halogens: The halogens are highly reactive, diatomic molecules. Reactivity of Halogens The halogens all form binary compounds with hydrogen, known as the hydrogen halides: hydrogen fluoride (HF), hydrogen chloride (HCl), hydrogen bromide (HBr), hydrogen iodide (HI), and hydrogen astatide (HAt).

The halogens or halogen elements are a group in the periodic table consisting of five chemically related elements, fluorine, chlorine, bromine, iodine, and astatine. The artificially created element 117 may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17. The group of halogens is the only periodic table group which contains elements in all three familiar states of matter at standard temperature and pressure.

Pseudohalogen  [show article only]hover over links in text for more info In the modern IUPAC nomenclature, this group is known as group 17. The name 'halogen' means 'salt-producing'. When halogens react with metals they produce a wide range of salts, including calcium fluoride, sodium chloride (common salt), silver bromide and potassium iodide.nterhalogen compounds are in the form of XY n where X and Y are halogens and n is one, three, five, or seven. Interhalogen compounds contain at most two different halogens. Large interhalogens, such as ClF 3 can be produced by a reaction of a pure halogen with a smaller interhalogen such as ClF.

Is Fluorine a Metal, Nonmetal or Metalloid? What is a halogenated compound? Quick Answer. A halogenated compound is a combination of one or more chemical elements that includes a halogen; halogens are a group of elements that include fluorine, astatine, chlorine, bromine and iodine. Halogens comprise the seventh column of the periodic table of the elements.

Groups : The elements in this group are all one electron short of having a complete s-p octet in their outer energy level. Any element that accepts electrons to form a complete octet is called a nonmetal. The halogens will typically take an electron from a metal or even a weaker nonmetal to complete the desired octet.

- Rare Earth Elements The halogens are five non-metallic elements found in group 17 of the periodic table. The term halogen means salt-former and compounds containing halogens are called salts. All halogens have 7 electrons in their outer shells, giving them an oxidation number of -1. The halogens exist, at room temperature, in all three states of matter: Solid- Iodine, Astatine; Liquid- Bromine; Gas- Fluorine, Chlorine; The Halogens are: Fluorine

All About the IUD Updated December 24, 2016. An IUD is a small, flexible contraceptive device that is inserted into the uterus. The letters IUD stand for intrauterine device. An IUD is usually made of plastic and is shaped like the letter T. This contraceptive method is long lasting, safe and extremely effective.
