Cations are formed when an atom loses one or more electrons, resulting in a positive charge. On the other hand, anions are formed when an atom gains one or more electrons, resulting in a negative charge. The terms cations and anions are essential in understanding chemical reactions. Cations and anions can combine to form ionic compounds.In anions, the number of electrons is more than the number of protons. 4. Generally, metals form cations. Generally, non - metals form anions. 5. Cations get attracted towards the negatively charged electrode in electrolysis. Anions get attracted towards the positively charged electrode in electrolysis. 6.Aluminum and carbon react to form an ionic compound.
