WebIn each case, a halogen higher in the Group can oxidise the ions of one lower down. For example, chlorine can oxidise the bromide ions (in, for example, potassium bromide solution) to bromine: Cl 2 + 2Br - 2Cl - + Br 2. The bromine appears as an orange solution. As you have seen above, chlorine can also oxidise iodide ions (in, for example ...

"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 ... " - Reactivity down group 7

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. WebOct 6, 2007 · Why do the reactivity of the group 1 atoms increase as you go down the group, but the reactivity of group 7 decreases as you go down the group. I get why it does in group 1, but I don't get why it does in group 7?? The answer lies in understanding what the atoms are trying to do.

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.

WebDec 21, 2024 · The melting points and boiling points of the halogens increase going down group 7. This is because, going down group 7: the molecules become larger. more energy is needed to overcome these forces. What is the trend in reactivity as you go down group 7? Reactivity decreases down the group.

WebThe fall in reactivity is because the halogens become less good oxidising agents as you go down the group. In the cases of chlorine and bromine, the iron atoms are oxidised to iron (III) ions.
