Which term describes a positively charged ion?

Explanation:
A positively charged ion is called a cation. It forms when an atom loses electrons, leaving more protons than electrons, which gives the atom a net positive charge. Metals often form cations, such as Na+ or Ca2+. In contrast, anions are negatively charged ions formed when atoms gain electrons. An electron is a negatively charged particle, and a proton is a positively charged particle, but ions are whole atoms or molecules with a net charge.
