A negatively charged ion; A positively charged ion

Explanation:
When atoms gain or lose electrons, they form charged particles called ions. If an atom gains electrons, it becomes negatively charged—that type of ion is an anion. If an atom loses electrons, it becomes positively charged—that type is a cation. So the negative ion is an anion and the positive ion is a cation, which is the pairing shown here. For context, Cl− is an anion and Na+ is a cation. The other options don’t fit because “Ion” is a general term for any charged particle, “Molecule” usually implies neutrality, and subatomic particles like protons or neutrons aren’t the ions described here.
