Determining the Oxidation Number

Postby Mayvera Doaran 2H » Fri Jan 29, 2016 5:00 pm

When we determine the oxidation number of a certain molecule in a reaction, do we take the oxidation number of a singular atom in that molecule?

For example, would the oxidation number for 2Cr2+ be +2 or +4?

Each atom of Cr is 2+, however, in the reaction if there are 2Cr2+, then the total for that part of the redox reaction would be 4+.
