Based on the oxidation states of the atoms in this reaction, answer the questions. 4Fe(0) + 3O2(0) → 2Fe2(3+)O3(2-) How many electrons does the iron half-reaction lose? How many electrons does the oxygen half-reaction gain? What is the total number of electrons that are moved in this oxidation-reduction reaction?

Twelve electrons

Explanation:

If we look at the product side, we will notice that iron lost twelve electrons and oxygen gained twelve electrons.

Hence, we have 4Fe^3+ and 2O3^2- showing twelve electrons lost/gained.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
