WebCommon forms are chromium-0, which has no charge, chromium+3, which has an ionic charge of plus 3, and chromium+6, which has a charge of plus 6. Chrome metal (the form chromium-0) is the element that makes steel “stainless.” Chromium in this form is hard, stable, and resistant to chemical changes such as oxidation or rust. 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.
