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.
an opening or hiatus. anion gap the concentration of plasma anions not routinely measured by laboratory screening, accounting for the difference between the routinely measured anions and cations and equal to the plasma sodium â (chloride + bicarbonate); used in the evaluation of acid-base disorders.
