Chapter 1, 1.6 Oxidation Numbers

Chapter 1, 1.6 Oxidation Numbers

Postby josybabe2421 » Sun Aug 10, 2014 12:45 pm

I'm having trouble solidifying the difference between Oxidation number and Ionic charge, can someone give me an example in which Oxidation number is different from Ionic charge?

An atoms ionic charge is given by the number of electrons it has lost or gained. Whereas Oxidation number is a representation of electrons lost or gained... I'm having trouble seeing the difference lol.

Any clarification would be great :) Its been ages since I did Chemistry and I didn't think I even completely understood this back then.

** Edit: I think I've worked it out, oxidation numbers are assigned even when an atom is sharing its electron? not giving it up?

Yes, you've got it!

The charge on ions represent the fact that electrons actually changed 'owners'. The oxidation number is not a charge. It is a theoretical value given to atoms within molecules. That value can be helpful in balancing reactions and in determining which atoms were oxidized or reduced in reactions.
