In terms of electrons, what happens to a species that is oxidized?
AIt gains electrons from another species
BIt shares electrons with another species
CIt loses electrons to another species
DIt keeps its electrons entirely unchanged
Answer & Solution
Correct answer: C. It loses electrons to another species
1. When sodium meets chlorine, the half-reactions show Na atoms losing electrons.
2. Loss of electrons is oxidation, so sodium is oxidized.
3. Chlorine atoms gain those electrons, which is reduction.
4. The two processes always happen together, since electrons lost by one species are gained by another.
