WebReaction of astatine with the halogens. Astatine, At 2, reacts with bromine, Br 2, or iodine, I 2, to form the "interhalogen" species AtBr and AtI respectively. Both of these dissolve in … WebBecause the atoms have a nearly equal electronegativity, and as the At+ ion has been observed, [5] dissociation could easily result in the hydrogen carrying the negative charge. Thus, a hydrogen astatide sample can undergo the following reaction: 2 HAt → H+ + At− + H− + At+ → H2 + At2 This results in elemental hydrogen gas and astatine precipitate.
