Reactivity of group 7 trend
Webreactivity trend down group 7 is? and why down the group the reactivity decreases because they need to gain an electron and down the group there are more shells, larger atomic radius and more shielding. So there is less nuclear force attracting the electron and so it … WebF 9 → 2, 7 Cl 17 → 2, 8, 7. And also they all have smaller atomic radii comparatively, which means they strongly attract electrons towards themselves; i.e., they are highly …

WebAug 21, 2024 · In each case, a halogen higher in the group can oxidize the ions of one lower down. For example, chlorine can oxidize bromide ions to bromine: (3) Cl 2 + 2 Br − → 2 Cl − + Br 2. The bromine forms an orange solution. As shown below, chlorine can also oxidize iodide ions to iodine: (4) Cl 2 + 2 I − → 2 Cl − + I 2. Web1 day ago · Saving the Overworld, one block at a time.
