Group 17 (VII) Halogens - Properties and Trends

In this video, we take a closer look at the halogens (Group VII (17) elements) and explore their physical and chemical properties. We'll focus on key trends such as how electronegativity and boiling points change as you move down the group. You'll also see their oxidizing ability in action with displacement reactions involving halide ions in solution. Finally, we’ll demonstrate the reducing ability of halide ions and discuss the importance of these trends in understanding the reactivity and behavior of halogens. Identifying halide ions using aqueous silver nitrate, dilute nitric acid and ammonia solution is shown.
