Which reaction shows oxidation by the loss of electrons?
For example, consider this reaction, which shows oxidation by the loss of electrons: Zn(s) ® Zn2+ (aq) +2 e— Notice that the zinc metal (the reactant) has an oxidation number of zero (rule 1), and the zinc cation (the product) has an oxidation number of +2 (rule 2).
What is the sum of oxidation numbers in a polyatomic ion?
This is also true for elements found in nature as diatomic (two-atom) elements: H2, O2, S8. 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.
