How does astatine react with hydrogen
Web(b) Astatine forms a diatomic molecule with the same type of bonding as in a chlorine molecule. Draw the ‘dot-and-cross’ diagram for an astatine molecule. Only draw the outer shell electrons. 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.
