4. Assigning Oxidation Numbers
0 for elements
+1 for Group 1
+2 for Group 2
-1 for Group 7 monatomic anions
+1 for Hydrogen (-1 in metal hydrides)
-2 for Oxygen (-1 in peroxides)

7. Redox Balancing: O & H in Base

8. Carbon Oxidation Numbers in Organic Molecules
Each bond to another carbon has no effect
Oxidation number decreased by one for each bond to Hydrogen
Oxidation number increased by one for each heteroatom bond (sigma and pi bonds)

13. Conclusions
For inorganic species, assign oxidation numbers to every atom
For organic molecules, add total heteroatoms to total degrees of unsaturation
Increasing oxidation number or oxidation level represents an oxidation
Decreasing oxidation number or oxidation level represents a reduction
