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).
20 wrz 2022 · The halogens all have the general electron configuration \(ns^2np^5\), giving them seven valence electrons. They are one electron short of having the full outer \(s\) and \(p\) sublevel, which makes them very reactive.
30 cze 2023 · This page discusses the trends in the atomic and physical properties of the Group 7 elements (the halogens): fluorine, chlorine, bromine and iodine.
The Halogens. There are six elements in Group VIIA, the next-to-last column of the periodic table. As expected, these elements have certain properties in common. They all form diatomic molecules (H 2, F 2, Cl 2, Br 2, I 2, and At 2), for example, and they all form negatively charged ions (H-, F-, Cl-, Br-, I-, and At-).
6 lis 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.
10 paź 2020 · There are six halogen elements: Fluorine (F) – Atomic number 9. Chlorine (Cl) – Atomic number 17. Bromine (Br) – Atomic number 35. Iodine (I) – Atomic number 53. Astatine (At) – Atomic number 85. Tennessine (Ts) – Atomic number 117. Here are chlorine, bromine, and iodine (left to right) at room temperature.
