Compounds that do not contain ions, but instead consist of atoms bonded tightly together in molecules (uncharged groups of atoms that behave as a single unit), are called covalent compounds. As this difference lies between 0.4 and 1.6, the bonds formed in the SO3 molecule are polar covalent bonds. Thanks for contributing an answer to Chemistry Stack Exchange!

No, So3 is an ionic bond because if you substrate the electronegivity of each. attraction between the temporary molecules; weakest, a strong attraction between a hydrogen atom on one molecule and an electronegative element on another molecule, Rank the three intermolecular from weakest to strongest, London Dispersion, Dipole-Dipole, Hydrogen Bonding. https://en.wikipedia.org/wiki/Ionic_bonding. Can Martian regolith be easily melted with microwaves? The ionic bonds are formed when the difference in the electronegativity of the atoms participating in the bond formation is greater than 1.6, while the covalent bonds are formed when the electronegativity difference is below 1.6. N2 + 3H2 --> 2NH3 + heat. The sulfur trioxide molecule is covalent as both the participating atoms i.e. So the difference in electronegativity is somewhere between 1.5 and 2.1, between a polar covalent bond and an ionic bond.
