However, I think it is because the molecule has a 2- charge, not necessarily each individual oxygen atom within that molecule. I do believe, however, that each individual oxygen atom does have a 2- oxidation state, which would total 14-, but then each chromium atom has a 6+ oxidation state, cancelling out 12 … progress has been made 意味
