Is Br2 A Gas, Accelerates the burning of combustible material. Other names: Br2; Brom; Brome; Bromo; Broom; UN 1744; Dibromine Permanent link for this species. , 1974, 51, 428. It is very corrosive to tissue and to metals. This process of extracting bromine from natural sources is an important aspect of the occurrence and preparation of halogens discussed in Section 18. Electronegativity and reactivity in comparison with other halides: It shows lower electronegativity and reactivity in comparison with chlorine, but higher when compared with iodine. The bromine gas is then collected and condensed into a liquid form. Bromine is a dark reddish-brown fuming liquid with a pungent odor.
