Halogens are toxic & corrosive – work in a fume hood or well-ventilated area.

Here’s a clear and engaging post about based on the typical Malaysian SPM curriculum (KSSM). The experiment usually focuses on Periodic Table – Reactivity of Group 1 (Alkali Metals) or Group 17 (Halogens) . experiment 4.2 chemistry form 4

Wear goggles & use small pieces only. Potassium reacts violently!

To determine the reactivity trend of Group 17 (chlorine, bromine, iodine). Wear goggles & use small pieces only

2M(s) + 2H₂O(l) → 2MOH(aq) + H₂(g) (Alkali metal + water → metal hydroxide + hydrogen)

Reactivity decreases down Group 17: Cl > Br > I Chlorine can displace bromine & iodine; bromine can displace iodine only.
