The formation of is the basis for the formation of xenon fluorides. This is because:
and
have comparable sizes.
Both and
are gases.
and
have comparable ionisation energies.
and
have comparable electronegativities.
The first ionisation energy of xenon is quite close to that of oxygen and the molecular diameter of xenon and oxygen are almost identical.
Based on the above facts it is suggested that since oxygen combines with , so xenon should also form similar compound with
.
