Reactivity going down group 7

WebFor group 1 Alkali metals- this means that the lower down the group the less energy needed to remove an electron so the easier it is to form positive ions/ easier to react. Now what about group 7 - halogens. These atoms will want to gain an electron to form a negative ion with a full outer shell. WebSep 2, 2024 · As you go down group 7, the halogens become less reactive. This is because: Decreasing reactivity, - Atomic radius increases. - Nuclear charge increases, so the …
