Video: Anion: Definition & Examples. Ions are charged particles that are important for biological and chemical systems. Anions are ions that have a negative charge. This article discusses anions, their properties, and examples of anions in chemistry and nature.
Remember that a cation is a positively charged atom or molecule (one that has lost one or more electrons) and that an anion is a negatively charged atom or molecule (one that has gained one or more electrons). The ions are held together by electrostatic attractions.
