Swapping of positive and negative ions in drawing

Hello, It looks like the positive and negative ions should be swapped in the skeleton drawing. Both Oxygen and Sulfur should have two bonds, but Sulfur has one electron extra, so it should have a negative ion, and according to the skeleton drawing, the Oxygen has a lack of an electron, so that should be positive. Also, the sphere-colour-drawing of the structure shows four bonds with sulphur and two bonds with oxygen.

As I see these (in my eyes) inconsistent things, I'd like them to be removed. However, I might have overlooked something. So if you agree with this statement, go ahead and change the image(s).

I'm looking forward to hearing from anyone of you.

I think the Sulphur Oxygen bond is a double bond but the pi bond has a mobile electron (from the Sulphur) which is being captured by the Oxygen. Hence the bond between the Sulphur and Oxygen is fluctuating between a double bond, on the one hand, and a single sigma bond plus a positive Sulphur and negative Oxygen, on the other hand. In other words, the functional group is fluctuating between these two states because of the mobility of this single electron from the Sulphur atom to the Oxygen atom and back to reform the pi bond. In other words, the functional group is a dynamic structure because of the constant breaking and reforming of this pi bond between the S and O atoms. Hence, in my estimation, you are right to point out that the bond between the Sulphur and Oxygen is a double bond but incorrect in stating that Sulphur should be negatively charged and Oxygen positively charged. 77.86.63.166 (talk) 21:30, 18 October 2022 (UTC)[reply]
