Understand the concept of oxidation in chemistry: Oxidation is defined as the loss of electrons by a molecule, atom, or ion.
Recall that reduction is the opposite process, which involves the gain of electrons.
Recognize that forming a covalent bond does not necessarily mean oxidation or reduction; it depends on the electron sharing and changes in oxidation states.
Identify that when a molecule loses electrons, its oxidation state increases, meaning it becomes more oxidized.
Therefore, the correct description of a molecule becoming more oxidized is that it loses electrons.
