WebNov 18, 2024 · The decrease in the reactivity down Group 17 can be explained as follows. All halogens have seven valence electrons. Each halogen atom will gain one electron to achieve a stable octet electron arrangement. Hence, an ion with a charge of -1 is formed. When going down Group 17, the atomic size of halogens increases. WebGroup 7 elements. Fluorine, Chlorine, Bromine, Iodine, Astatine. All group 7 elements are diatomic in nature. What is the trend in reactivity going down group 7? -going down group 7, reactivity decreases. -this is because atomic shielding increases going down the group, meaning out electron is further away from nucleus.
