  1. Remember the definitions.
    Oxidation is the loss of electrons.
    So Cu goes from +1 to zero and iron goes from zero to +2. Which loses electrons?

  2. Hi, I'm a 10th grade student and this is how I would look at it...
    So what is being oxidized is what is losing electrons.

    So take Copper for example.
    Copper is going from a 1+ charge to no charge as a solid...so is it gaining an electron or losing.

    Now think of Iron.
    Iron is going from no charge to a charge of 2+. So would that be losing electrons or gaining?

    Whichever element loses the electrons would be oxidized in this reaction.

    Hope this helps!
