~Also called: Oxidation-Reduction Reactions
~Transfer of one or more electrons from one reactant to another.
- ~The loss of electrons from one substance is called OXIDATION.
- ~The addition of electrons to another substance is called REDUCTION
- ~Reducing Agent: Electron donor
- ~Oxidixing Agent: Electron acceptor
~Oxidation and Reduction ALWAYS go hand in hand
~Not all redox reactions involve the complete transfer of electrons from one substance to another
~Oxygen is one of the most potent oxidizing agents because it's so electronegative
~Energy MUST be added to pull an electron away from an atom
