Radon difluoride (RnF
2) is a compound of
radon, a radioactive
noble gas. Radon reacts readily with
fluorine to form a solid compound, but this decomposes on attempted vaporization and its exact composition is uncertain.
[1]
[2] Calculations suggest that it may be
ionic,
[3] unlike all other known binary
noble gas compounds. The usefulness of radon compounds is limited because of the
radioactivity of radon. The longest-lived
isotope,
radon-222, has a
half-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 and hydrogen fluoride when heated with hydrogen gas at 500 °C. [1]
