WebJul 5, 2024 · The reactivity decreases down group 7. Group 7 elements have 7 valence electrons (electrons on the very last electronic shell), so this means it need to attract one electron (because its harder to lose 7 than attract 1) … 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 …
WebMar 18, 2011 · Why does the reactivity of group 7 elements decrease as you go down the table? Is due to the increase in the force of attraction between the nucleus and the outer most electrons. Related questions 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.
