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 ... 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.

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.

Reactivity down group 7

WebAs with group 1 and 2, the trends in properties and GENERAL reactivity in group 7 can be explained by their electronic configuration: The reason that melting and boiling points increase down the group is because the intermolecular forces between the halogen molecules (e.g. F 2, Cl 2, Br 2) get stronger down the group. http://passmyexams.co.uk/GCSE/chemistry/trends-in-halogens.html
