Oxidation Rules 
Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) 
-Mg=0,H2=0, C=0 
 
Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion 
-Mg^2+=+2, Na^+=+1, O^2-=-2 
 
Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. 
 
Rule 4: The oxidation numb...
