An anion is an ionic species having a negative charge. They are atoms that have gained electrons. Anions are one of the two types of ions. The other type is called a cation. Anions are attracted to the anode, while cations are attracted to the cathode. The concept of an anion is important in the corrosion industry because certain anions facilitate corrosion.
A negatively charged ion, which has more electrons in its electron shell that it does have in protons in its nucleus, is known to us as anions ( an-i-ons ). Most anions are nonmetallic.* Conversley, a positive charged ion is formed when an atom has fewer electrons that it does have with protons in the nucleus. The ion is
