Its chemical formula is TlBr. It has [[thallium]] and [[bromide]] [[ion]]s in it. The thallium is in its +1 [[oxidation state]]. ==Properties== Thallium(I) bromide is a yellow-white solid. It is similar to [[silver bromide]]. It gets darker when light shines on it. It is very toxic, like all thallium compounds. It does not dissolve in water. ==Preparation== Thallium(I) bromide is made by reacting thallium and [[bromine]] or by reacting [[sodium bromide|sodium]] or [[potassium
