There are 2 resonance structures for ozone.
There are two resonance structures that can be drawn for ozone (O3), where the double bond alternates between the two oxygen atoms.
Unlike sulfur dioxide, selenium dioxide is polymeric, so if you drew resonance structures for charged forms there would be an awful lot!
Ozone has two resonance structures.
[O=O-O] <--> [O-O=O]

There are two resonance structures that can be drawn for O3 (ozone). This is because there is a double bond that can be delocalized between different oxygen atoms, resulting in two possible arrangements of bonds.
There are two resonance structures that can be drawn for the carbonate ion (CO3^2-).
There is only one resonance structure for BeF2 since beryllium (Be) does not form multiple bonds due to its electron configuration (2 valence electrons). Therefore, the Lewis structure of BeF2 shows two single bonds between beryllium and each fluorine atom.
There is only one resonance structure for BCl3. Boron is attached by three single bonds to the three Chloride atoms and there are three lone pair electrons around the chlorine atoms. There are no resonance structures because they are all single bonds.
There are three resonance structures possible for the permanganate ion (MnO4-).
There are two resonance structures that can be drawn for O3 (ozone). This is because there is a double bond that can be delocalized between different oxygen atoms, resulting in two possible arrangements of bonds.

Three different resonance structures can be drawn for the sulfite ion (SO3^2-), where the double bond can be placed between sulfur and each of the three oxygen atoms.
There are two resonance structures that can be drawn for the carbonate ion (CO3^2-).

Multiple valid electron dot formulas can be written when a resonance structure occurs, typically at least two. These resonance structures show the delocalization of electrons within a molecule, leading to stabilization.
There can be multiple valid electron dot structures when resonance occurs, all representing the same molecule or ion. The actual structure is a combination, or hybrid, of these resonance structures.
The chloride ion (Cl-) has only one resonance structure. The electron arrangement around the chloride ion is stable and not delocalized, so there is no need for multiple resonance structures.
There is only one resonance structure for BeF2 since beryllium (Be) does not form multiple bonds due to its electron configuration (2 valence electrons). Therefore, the Lewis structure of BeF2 shows two single bonds between beryllium and each fluorine atom.
The best resonance structure of the phosphate ion has one double bond and three single bonds. The double bond is between the central phosphorus atom and one of the oxygen atoms.
