Reactivity down group 7

WebReactivity of halogens The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the group. This is the opposite trend to that seen in the alkali … WebThe halogens are non-metals and when non-metals react with metals, they GAIN the electrons that the metals lose. As you move down group 7, the atomic radius get bigger (more protons, more electrons, more shells) and so the negatively charged electrons in the outer shell move further away from the positively charged nucleus.
