onic bonds are formed through the attraction of opposite charges to each other. With that said, O=O would have covalent bonds as there is no difference in charge between the two Oxygen atoms. What would be another example of an ionic bond?

What possible error(s) exist in the Lewis structure (assume we are trying to represent the best
possible Lewis structure for the NO₂S ion knowing N is the central atom in this polyatomic ion)?
[:ö==S:
N=
CO
:O:
The best structure would have double bond and two lone pairs on each oxygen atom and a single bond with
three lone pairs on the sulfur.
There are no errors. This is the best possible structure.
The Lewis structure above does not minimize formal charges, thus is the not the best possible structure.
The nitrogen atom has an expanded octet, and this structure is impossible.
The Lewis structure contains the wrong number of electrons, thus this structure is impossible.
