WebSep 4, 2024 · Chlorine is more reactive than both bromine and iodine. Why is iodine the least reactive? When the atoms form ions, the incoming electron is held by a weak … WebDiscussions of the chemistry of the elements in Group VIIA therefore focus on four elements: fluorine, chlorine, bromine, and iodine. These elements are called the halogens (from the Greek hals, "salt," and gennan , "to form or generate") because they are literally the salt formers. None of the halogens can be found in nature in their elemental ...
WebAnswer (1 of 2): Yes, chlorine is more reactive than bromine because the chlorine atom has fewer shells and the electronic bonding is much stronger. The electrons are held closer to … WebThe order of reactivity is chlorine > bromine > iodine. This is because chlorine could displace bromine and iodine, bromine could only displace iodine, but iodine could not...
WebHere the apparent order of reactivity is not that predicted from their position in the Group (that is chlorine → bromine → iodine). This is because of the different physical states of … WebApr 10, 2024 · The smallest depletion occurs in the tropical region, and largest occurs in the polar regions, especially in the lower stratosphere in the Antarctic (see Figures S10 and S11 in Supporting Information S1), which is mainly caused by the coupling between iodine and other reaction cycles including chlorine, bromine, O x, NO x, and HO x.
