What is the oxidation number of chromium in K2 (Cr(CN) 2(O) 2
WebI 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 of those negative charges (because there are two chromium atoms), thus resulting in the 2- overall charge of the molecule. Someone please correct me if I'm wrong!
