WebbThe reactivities of the halogens (17th group) decrease down the group ( At < I < Br < Cl < F). This is due to the fact that atomic radius increases in size with an increase of … WebbI think I accidentally described why reactivity increases as you go from left to right across a row, just out of habit, since that question is so often associated with why reactivity …
Webb20 jan. 2024 · because group 7 have 7 electrons on its outer shell so they dont need to lose any electrons also the forces of attraction between + nuclei and electrons increase … WebbThe group 7 elements are the so-called halogens. They exist under normal circumstances in their molecular form ( $\ce{F2}$ , $\ce{Cl2}$ and so on). In contrast to the group 1 elements, the dominant intramolecular force here is London dispersion (or van der Waals forces if you prefer).
WebbAs we descend Group 7, the reactivity decreases. For stability, the atom needs to have a full outer shell. Group 7 elements need to gain 1 electron to have a full shell. As a result, a... Webb8 okt. 2024 · Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus. Why does atomic radii decrease as atomic number increases?
WebbA halogen displacement occurs when a more reactive halogen displaces a less reactive halogen from an aqueous solution of its halide; The reactivity of Group 7 non-metals increases as you move up the group; Out of the 3 halogens, chlorine, bromine and iodine, chlorine is the most reactive and iodine is the least reactive
WebbAs you go down group 7, the atomic radius increases and it becomes more difficult to attract another electron. Why does boiling point decrease down group 7? This is because, going down group 7: the molecules become larger. the intermolecular forces become stronger. more energy is needed to overcome these forces. courtview sidneyWebbOne of the other reasons that the Halogens decrease in reactivity down the group as the size of the atomic radius increases with an increase in the electronic energy level. As, down the group, the amount of electron shielding increases, and the electron becomes less attached to the nucleus.
