30 cze 2023 · All halogens form Group 1 salts with similar properties. In these compounds, halogens are present as halide anions with charge of -1 (e.g., Cl -, Br -, etc.). Replacing the -ine ending with an -ide ending indicates the presence of halide anions; for example, Cl - is named "chloride."

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.
20 wrz 2022 · 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.
All halogens 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). All of these compounds form acids when mixed with water.
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-).

18 maj 2018 · 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.
