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.
Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
