WebWhen a halogen atom reacts it will usually gain an electron, to form a 1- ion (X + e- → X-) The oxidation number has decreased from 0 to -1, therefore reduction has occurred. Therefore halogens will act as oxidising agents. Down Group 7 we have seen that the atoms become larger so the outer electrons are further away and are therefore more ...

WebFeb 8, 2024 · The reactivity of Group 7 elements decreases down the group. The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron.
