Oxidation is the process of

Explanation:
Oxidation is the loss of electrons. When an atom or ion loses electrons, its oxidation state becomes higher (more positive). For example, magnesium can lose two electrons to become Mg2+, showing oxidation. Gaining electrons would be reduction, not oxidation. Losing protons would change the identity of the element, not the redox process, and gaining neutrons changes isotopes in the nucleus, not the electron count. So the best description is the loss of electrons.
