By definition, the option E. is false: Oxidation is the process by which an atom loses electrons.
Oxidation is a reaction where an atom, ion or molecule loses electrons while reduction corresponds to the gain of electrons from an atom, ion or molecule.
Both oxidation and reduction depend on the change in the oxidation state of the atom, that is, on the difference in the charge of the atom in a reaction.
The oxidation and reduction reactions always occur simultaneously for what are generally known as oxidation-reduction reactions or redox reactions.
That is, reduction-oxidation reactions (also known as redox reaction) are electron transfer reactions. This transfer occurs between a set of chemical elements, one oxidizing and one reducing.
The reducer is that chemical element that tends to give electrons from its chemical structure to the environment, leaving it with a positive charge greater than the one it had.
The oxidant is the chemical element that tends to capture those electrons, leaving it with a lower positive charge than it had.
Finally, the option E. is false: Oxidation is the process by which an atom loses electrons.
