What is the molecular geometry for XeO3?
XeO4 is tetrahedral. The total number of valence electrons in
the molecule is 32 (6 x 4 oxygens and 8 from the Xe) which when
divided equally among the oxygens with a double bond to the Xe
gives every O molecule a full outer shell, and the Xe an extended
shell. If XeO4 (4-), then each O would be single-bonded to the
Xe.
