This article picks up from Non-Linear Optimization using Extensions to LP and continues an exploration of what can be achieved using extensions to Linear Programming.
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 cation has a positive charge. Todd Helmenstine. Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valence electrons giving the ion a net positive or negative charge.Cations are ions with a net positive charge.ations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion.
