Which term describes a negatively charged ion?

Explanation:
A negatively charged ion forms when an atom gains electrons. Electrons carry negative charge, so adding them gives the whole species a net negative charge, making it an anion. The other options aren’t right for describing a negatively charged ion: a proton is a positively charged particle in the nucleus, an electron is a negatively charged particle but not an ion by itself, and a cation is a positively charged ion. So the term for a negatively charged ion is an anion.
