- Halogens - Symbols, Properties and Reactions - CK-12 Foundation
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 The halogens all have the general electron configuration ns2np5, giving them seven valence electrons They
- Halogens: The Versatile Elements Shaping Our World
The halogens are a group of chemical elements in Group 17 of the periodic table, consisting of fluorine, chlorine, bromine, iodine, and astatine These highly reactive elements play a crucial role in various chemical processes, making them versatile and essential in shaping our world What are Halogens and Their Properties? Halogens are defined as a group of non-metal elements that exist in
- Halogens | Resource | RSC Education
The halogens, group 7, are an important group of elements both chemically and socially They are unusual in that they are coloured and diatomic They also have an order of reactivity that is the opposite of the metals in groups 1 and 2 In fact they are all very reactive,
- 18. 11 Occurrence, Preparation, and Properties of Halogens - OpenStax
Properties of the Halogens Fluorine is a pale yellow gas, chlorine is a greenish-yellow gas, bromine is a deep reddish-brown liquid, and iodine is a grayish-black crystalline solid Liquid bromine has a high vapor pressure, and the reddish vapor is readily visible in Figure 18 60 Iodine crystals have a noticeable vapor pressure When gently heated, these crystals sublime and form a beautiful
- What are halogen elements? | Britannica
The halogen elements are the six elements in Group 17 of the periodic table Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts) Astatine and tennessine are radioactive elements with very short half-lives and thus do not occur naturally

- Halogen Characteristics - Sciencing
The halogens are chemical elements that constitute Group 17 of the periodic table The six non-metallic elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (As) and tennessine (Ts) The name "halogen" comes from a Greek word meaning "salt-producing," since fluorine, chlorine and iodine produce a sea salt-like substance when they form a compound with an alkaline metal
- Halogen Properties - BYJUS
Halogens are nonmetals At room temperature, fluorine and chlorine are gases, bromine is a liquid and Iodine and astatine are solids Halogens are very reactive, the reactivity decreases from fluorine to astatine Halogens do not exist in elemental form in nature Astatine isotopes are radioactive with short half-lives Table salt, bleach, fluoride in toothpaste, and chlorine in swimming pools
