Oxidation numbers can be confusing, unless you think of it as charge (real or imaginary) associated with each specific atom in a complex molecule or polyatomic ion.

This video shows you how to find and calculate oxidation numbers when given simple and complex molecules or ions.

Calculating Oxidation Numbers Video 2 – Oxidation Numbers
Oxidation and reduction cannot happen on their own. When one atom loses electrons, another atom has to gain these electrons.
This video walks you through redox pairs using the mnemonic LEO the lion says GER to help you understand oxidizing/reducing agents. You’ll also learn how to recognize (rather than memorize) common oxidizing and reducing agents.
If you're looking to understand how assigning oxidation numbers can help you in studying things like the Galvanic/Voltaic or Electrolytic Cell, make sure to take a look at my Electrochemistry series.

Hi Leah, Thank you so much for all of your videos and resources. I love your teaching style! I just completed your stoichiometry series and you referred to your “Should versus Has” shortcut several times but I have not been able to find where you teach this elusive but apparently important method! Can you direct me or give me a link? Thanks so much. Christy
