WebAug 15, 2024 · As reducing agents, the halide ions follow the trend in reducing strength: (5) I − > Br − > Cl −. Conversely, the halogens follow the opposite order of oxidizing strength: Thus pale green Cl 2 oxidizes Br − to red Br 2 and I − to violet I 2. These colors are … WebAug 21, 2024 · However, halogens readily combine with most elements and are never seen uncombined in nature. As a general rule, fluorine is the most reactive halogen and astatine is the least reactive. 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.).
