Radon difluoride (RnF
2) is a compound ofradon, a radioactivenoble gas. Radon reacts readily withfluorine to form a solid compound, but this decomposes on attempted vaporization and its exact composition is uncertain.[1][2] Calculations suggest that it may beionic,[3] unlike all other known binarynoble gas compounds. The usefulness of radon compounds is limited because of theradioactivity of radon. The longest-livedisotope,radon-222, has ahalf-life of only 3.82 days, which decays by α-emission to yield polonium-218.[4]
When radon is heated to 400 °C with fluorine, radon difluoride is formed.[1]
Radon difluoride can be reduced to radon andhydrogen fluoride when heated withhydrogen gas at 500 °C.[1]
