In short: This video explains the fundamental mechanics of redox reactions, exploring how the movement of electrons defines the difference between oxidation and reduction.

A redox reaction, short for oxidation-reduction, is defined by the transfer of electrons between substances. While the term 'oxidation' originally referred to an element or compound gaining oxygen atoms, modern chemistry understands it as the process of an atom losing electrons. Conversely, the atom that gains those electrons is said to be reduced.
