Why does reactivity *increase up* group 7, but *increase down

WebAs you go down the Group, the ease with which these hydrated ions are formed falls, and so the halogens become less good as oxidising agents - less ready to take electrons from something else. The reason that the hydrated ions form less readily as you go down the Group is a fairly complicated mixture of several factors. WebMar 12, 2024 · The reactivity of the elements of Group 7 reduces the group downwards. Non-metal atoms gain electrons when they react with metals. This weaker attraction makes it harder for larger atoms to accumulate electrons. Elements of group 7 react vigorously with elements of group 1, such as sodium and potassium. Does reactivity increase …
