Verified step by step guidance1
Understand the concept of oxidation in chemistry: Oxidation is the process where an atom, ion, or molecule loses electrons.
Recall that electrons are negatively charged particles located in the electron cloud surrounding the nucleus of an atom.
Recognize that protons and neutrons are located in the nucleus and are not lost during oxidation; protons define the element, and neutrons contribute to the atomic mass.
Note that photons are particles of light and are not components of atoms, so they are not lost during oxidation.
Conclude that during oxidation, the particles lost by an atom are electrons, as this loss increases the oxidation state of the atom.
