Element Bohr Diagram Group Number (PT). So in this case, both resonances structures contribute equally to the final structure of the molecule. I expect structure 3 to be rare because of the high formal charges, but shouldn't it be included as a possible resonance structure? Furthermore, there is disagreement about whether structure 1 or structure 2 is more common. In (quantum) reality, however, the sulfite ion has what is called a 'resonance' structure, which is to say that the 'two-negative' ionic charge is actually spread out over all three oxygen atoms, since all electrons are in constant motion, and electron 'orbitals' are simply (ha ha) three-dimensional probability functions rather than actual. Author: John Hutchinson. Yes, this structure has resonance because the structure described is not adequate for accurately giving us a picture of the molecule.
