An element that is a member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23. With a valence of 1, it has a strong affinity for oxygen and other nonmetallic elements. Sodium provides the chief cation of the extracellular body fluids. Its salts are the most widely used in medicine. (From Dorland, 27th ed) Physiologically the sodium ion plays a major role in blood pressure regulation, maintenance of fluid volume, and electrolyte balance.

It is one of the alkali metals, of a silvery white color, waxy at ordinary temperature, melting at 95.6 C., and volatilizing at a red heat. It readily oxidizes on exposure to moisture, decomposes water with evolution of heat, and unites with potassium to form an alloy. It forms soluble salts with all of the acids. Atomic weight, 23. Symbol, Na. Specific gravity, 0.972.
