Ionic radon solutions.
Radon is oxidized between -195 degrees and 25 degrees C by chlorine fluorides, bromine fluorides, iodine heptafluoride, and NiF(6)(2)- ion in hydrogen fluoride with the formation of stable solutions of radon fluoride. Electromigration studies show that the radon is present as a cation, possibly Rn(2)+ or RnF+, in several conducting solutions.
