We will study the importance of group 17 elements, their properties, and their uses in this article. Some of the classic uses of halogens are as follows: Iodine is used as an antiseptic, chlorine is a. Group - 17 elements (Halogens) Introduction : → The elements of this group are Fluorine (F), Chlorine (Cl), Bromine (Br), lodine (I), and Astatine (At). All the elements of this group are non-metallic in nature. Collectively these elements are known as halogens. Halogen is a Greek word (halo sea salts; gens = producing) whose meaning sea salt forming Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to high electronegativity and high effective nuclear charge. Halogens can gain an electron by reacting with atoms of other elements. Fluorine is one of the most reactive elements halogen elements are: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The artificially created element 117, tennessine (Ts), may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 1
Halogens are the salt-producing elements. This category contains some of the most useful elements because, when halogens react with metals, they form a variety of salts. Without halogens, we wouldn't have sodium chloride, which is the salt we eat. This quiz game will help you learn the halogens quickly List of all Halogens. The halogen family includes fluorine, chlorine, bromine, iodine, astatine, and tennessine, element 117 - the most recent element to be discovered.

The forces between these molecules are called Van der Waals forces. However, in water the hydrogen molecules are the most prominent The halogens are the five chemical elements that make up Group 17 on the periodic table: fluorine, chlorine, bromine, iodine, and astatine. The term halogen comes from Greek terms meaning to produce sea salt. The halogens are all chemically active. For that reason, none occur naturally in the form of elements
Halogens. The halogen elements are a subset of the nonmetals. They comprise group 17 of the periodic table, from F through At. They generally very chemically reactive and are present in the environment as compounds rather than as pure elements. Noble gases Halogens are highly reactive non-metals and have a great resemblance in their properties. Collectively, the Group 17 elements are called halogens (In Greek, the halo is described as salt, genes - means producing, so collectively it can be given as salt-producing). These elements are chlorine, fluorine, bromine, astatine, and iodine The halogens include fluorine, chlorine, bromine, iodine, and astatine. All of these elements are considered to be reactive nonmetals. All members of the halogen family have seven valence electrons.
