Reactivity going down group 7
WebWhy does the reactivity of group 7 elements decrease down the periodic table? As you go down the group, the outer electrons are further from the nucleus, this leads to a reduced … WebJan 20, 2024 · With group 7 elements, the outer shell has 7 electrons. This means that an electron must be gained. Electrons are attracted to the nucleus, therefore if there is a short distance between the outer shell and the nucleus, it will react more. As you go down the group, there are more electron shells which causes shielding as electrons repel. The more …
Reactivity going down group 7
Did you know?
WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive. Is as follows: To remember how the reactivity of the alkali metals and halogens increases or decreases, put a pin in the middle of the periodic table and spin it anti-clockwise. WebAs you move down group 7, the boiling point increases. 1. The number of electrons increases, leading to an increase in Van der Waals forces between molecules. 2. Therefore more energy is needed to break the bonds, so hence a higher boiling point. top Redox reactions and trends in reactivity of Group 7 elements and their compounds

WebJul 5, 2024 · Reactivity of Group 7 non-metals increases as you go up the group. Out of the 3 halogens, chlorine, bromine and Iodine, chlorine is the most reactive and iodine is the least reactive. Which is more reactive bromine or iodine in Group 7? Bromine is above Iodine in Group 7 so is more reactive.
