WebMar 3, 2024 · Cations and anions are the two types of ions. Ions have an imbalance of electrical charge, meaning they contain different numbers of protons and electrons. Cation have a positive electrical charge and have more protons than electrons. Anions have a negative electrical charge and have more electrons than protons.
