New evidence that radon is a metalloid element: ion-exchange reactions of cationic radon
Abstract
Cationic radon in 1,1,2-trichlorotrifluoroethane displaces hydrogen, sodium, and potassium ions in solid materials, such as Nafion resins (H+ and K+ forms), potassium hexafluorophosphate, and sodium hexafluoroantimonate; radon in this state can be quantitatively collected by ion-exchange and eluted with bromine trifluoride in sulphuryl chloride.
