When Potassium Bromide is dissolved in water (polar solvent), it forms a neutral solution. Atoms of group 17 gain one electron and form anions with a 1 charge; atoms of group 16 gain two electrons and form ions with a 2 charge, and so on. (Br1-) However, bromine can from a cation, as is the case when using N-bromosuccinimide . [30], The halogens form many binary, diamagnetic interhalogen compounds with stoichiometries XY, XY3, XY5, and XY7 (where X is heavier than Y), and bromine is no exception. [31] Bromine monochloride (BrCl), a red-brown gas, quite readily dissociates reversibly into bromine and chlorine at room temperature and thus also cannot be obtained pure, though it can be made by the reversible direct reaction of its elements in the gas phase or in carbon tetrachloride. As this ionic substance reacts with the electrodes it generates electrical current. City Of Covington Utilities Phone Number, Most polyatomic ions combine with oxygen and/or hydrogen to make an anion. "Cation vs Anion: Definition, Chart and the Periodic Table".
