To form an ionic compound you need to form both a positively charged ion (cation) and a negatively charged ion (anion). Metals are the most likely candidates for forming cations because they typically have low ionization energies, so it won't be too difficult (i.e. won't cost that much energy) to remove electrons from them. Of all the elements, the ones that are most likely to form anions are the non-metals (excluding the noble gases), because they typically have large electron affinities, meaning they give off a lot of energy when you add an electron (or electrons) to them. So to find out which compounds are ionic, look for compounds made up of a metal and a non-metal. Those would be: FeO, Li2O, SrO, and K2O Covalent compounds are typically formed whenever you have two elements who are so similar in their ability to attract electrons that neither is dominant enough to take the electron from the other (kinda). Covalent bonds can form both from two (or more) non-metals or from two (or more) metals. Covalent metal bonds are usually classified as a special kind of covalent bond called a metallic bond. So the elements that are covalent (all non-metal/non-metal examples) are: CO2, N2O4, and XeO3.
XeO3
XeO3
Formula: XeO3
XeF4+H2O->XeO3+HF+H2O
Xenon oxides such as XeO2 or XeO3 or XeO4 could be formed depending on the temperature.
Xenon trioxide has a trigonal planar shape.
The chemical name for XeO3 is xenon trioxide.
XeO3
XeO3
Formula: XeO3
XeO3 has two names under the IUPAC naming convention, xenon trioxide and xenon(VI) trioxide. This unstable compound is also known as xenic anhydride.
Examples: XeF2, XeO3, XeOF2.
XeF4+H2O->XeO3+HF+H2O

Xenon does not have to follow the octet rule because of its access to the 4d sublevel. The Lewis structure of XeO3 places a Xe in the center, double bonded to three O atoms and with one lone pair on the Xe.
in XeO3 ,Xe shows sp3 but shape is pyramidal because of the presence of a lone pair of electrons on the central xenon atom. This lone pair distorts the shape of the molecule making it pyramidal.
