A definition of the term "potassium" is presented. It refers to a soft, silver-white, waxlike metallic chemical element that serves as both the principal cation in intracellular fluid and an important electrolyte in extracellular fluid. Potassium is found in cereals, dried peas and beans, fresh vegetables, fresh or dried fruits.
