A molecule becomes more oxidized when it:

• A. loses electrons
• B. forms a covalent bond
• C. is reduced
• D. gains electrons

Answer: (A)

Verified step by step guidance

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