WebI had the same question when I first watched this video. 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 …

WebSep 3, 2008 · 1. Find out which element is reduced (Its oxidation number decreases). The oxidation number of Cr in Cr2O7^-2 is found by assigning -2 as the oxidation number of O, and x to Cr: 2x + (-2) (7) = -2 (the -2 on the right side is the ionic charge) Solving for x we get x = +6.
