Verified step by step guidance1
Identify the elements present in the compound. Here, Xe is xenon, a noble gas, and O is oxygen.
Determine the number of oxygen atoms bonded to xenon. The formula XeO_3 indicates there are three oxygen atoms.
Recall the naming convention for molecular compounds involving nonmetals: use prefixes to indicate the number of atoms (mono-, di-, tri-, tetra-, etc.). Since there are three oxygen atoms, the prefix 'tri-' is used.
Combine the element names with the appropriate prefixes: 'xenon' for Xe and 'trioxide' for three oxygen atoms.
Thus, the correct name for XeO_3 is 'xenon trioxide'.
