In general, the ionization energy increases moving up a group and moving left to right across a period. Moreover: Ionization energy is lowest for the alkali metals which have a single electron ... Webbromine + potassium iodide → potassium bromide + iodine. Br2 + 2KI → 2KBr + I2. This table shows a summary of the displacement reactions of the halogens: chlorine, bromine and iodine. From this pattern of reaction we can predict that: Fluorine will displace all other halogens from their compounds. Astatine will be displaced by all the ... megality stonehenge
