Radon difluoride

Radon difluoride (Template:Chem) 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.<ref name="Stein 62">Template:Cite journal</ref><ref>Template:Cite journal</ref> Calculations suggest that it may be ionic,<ref>Template:Cite journal</ref> 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.<ref>Template:Cite book</ref>

Preparation

When radon is heated to 400 °C with fluorine, radon difluoride is formed.<ref name="Stein 62" />

Reactions

Radon difluoride can be reduced to radon and hydrogen fluoride when heated with hydrogen gas at 500 °C.<ref name="Stein 62" />
