29 Οκτ 2024 · 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.
6 Νοε 2019 · 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. As pure elements, they form diatomic molecules with atoms joined by nonpolar covalent bonds. The chemical properties are more uniform.
20 Σεπ 2022 · 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?
10 Οκτ 2020 · The halogens share several common properties: All of the halogens are nonmetals. They are poor conductors of heat and electricity and form brittle solids. Atoms of halogen elements have seven valence electrons in their outer shell. This is one less electron than needed for a full valence shell, so their usual oxidation state is -1.
The halogens exist as simple. molecules. Each molecule contains two halogen. atoms. joined by a single. covalent bond. The table shows the colour and physical. states. of chlorine, bromine and...
13 Σεπ 2022 · General Characteristics. The element of group VIIA exhibits similarity in the following properties: Electronic configuration: all elements have seven electronic (ns2np5) in their outermost shell. According to Hund’s rule, the five p-electrons are arranged in orbitals as px2, py2, and pz1. Fluorine and chlorine gases exist as gases.
