Difference Between Bromine and Chlorine | Difference Between

Bromine is less reactive than chlorine. However, under normal conditions, bromine participates in multiple chemical interactions. Often in the chemical compounds bromine exhibits a -1 oxidation state, but it can also be in any odd positive oxidation state (+1, +3, +5, +7). Chlorine can be present in all oxidation states from -1 to +7, except +2.

Bromine can also be found as an alternative to chlorine in swimming pools. Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire). Some bromine-containing compounds were historically used as sedatives (drugs that can make people calm or sleepy).
