Reactivity down group 7

WebMay 27, 2024 · The reactivity of Group 7 elements decreases down the group. Non-metal atoms gain electrons when they react with metals. When a halogen atom reacts, it gains one electron into their highest occupied energy level (outer shell) to form a singly negative charged ion. Also, what is special about Group 7 in the periodic table? 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.

How does reactivity change as you go down a group?

WebAs you go down group 7, reactivity of the halogens decreases because: The atomic mass of the halogens increases. They increase in electron shells; so the atoms are larger as you … 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. 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 ... binary diff/patch utility
