Oxygen Is Loss of electrons
Reduction Is Gain of electrons
If something goes from + to - then it has gained electrons
If something goes from neutral to - it has gained electrons
If it goes from - to + is loses electrons
If it goes from neutral to + it loses electrons
If something is oxidised, it is a reducing agent
If something is reduced, it is an oxidising agent
