The Lewis structure for the SO₄^2- ion contains how many "bonding electrons"?

Question

Quizplus · Accepted Answer

The SOS ion, also known as the thiosulfate ion, has a chemical formula of $S_2O_3^{2-}$. In its Lewis structure, there are two sulfur-oxygen double bonds and one sulfur-sulfur single bond. Each double bond consists of 4 bonding electrons (2 pairs), and the single bond consists of 2 bonding electrons (1 pair). Therefore, the total number of bonding electrons is $4+4+2=10$, which is not an option provided. However, based on the choices given, the closest correct interpretation of the question seems to be a mistake, as none of the options accurately reflect the correct number of bonding electrons for the thiosulfate ion. Given the options, the explanation provided doesn't match any of them directly due to a misunderstanding in the question's formulation or a typographical error in the options.
