Which process describes the loss of electrons?

• A. Reduction
• B. Oxidation
• C. Ionization
• D. Hydration

Answer: (B)

Loss of electrons is oxidation. In redox chemistry, one species becomes oxidized when it loses electrons, increasing its oxidation state, while another species is reduced by gaining those electrons. For example, a metal atom turning into a metal ion (like Zn → Zn2+ + 2 e−) embodies oxidation because electrons are shed. Those electrons are typically transferred to another species that is reduced, illustrating the paired nature of oxidation and reduction. Hydration involves water binding and does not involve electron transfer, while ionization is the removal of electrons to form charged particles, which is a separate concept and not the standard description of electron loss within a chemical reaction.
