Explanation

Two oxides of xenon are known:

• xenon trioxide (XeO3) 
• xenon tetroxide (XeO4)

They both are unstable, highly explosive solids that must be handled with the greatest care.

The oxide fluorides XeO3F2, XeO2F4, XeOF4, XeO2F2, and XeOF2 are known and, except XeOF4, all are thermodynamically unstable.
