解释： Cations are ions that carry a positive charge. They are formed when an atom or molecule loses one or more electrons. In chemical reactions, cations are attracted to anions, which are ions that carry a negative charge. Together, cations and anions form ionic compounds, such as salts, which are held together by electrostatic forces.
