How does astatine react with hydrogen
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. WebAstatine should react very slowly with hydrogen, even when heated. A small amount of hydrogen astatide should form, which dissolves in water to form an acidic solution.
