Sodium. body-centered cubic (bcc) Sodium is a chemical element with an atomic number of 11. Its symbol is Na (from its Latin name natrium ). It is an alkali metal. Although sodium has many isotopes, most decay in a short time. Because of this, all sodium in nature (mainly found in seawater) is of the isotope 11 Na 23.
Sodium and Water Balance. Sodium is the primary cation (positively charged ion) in extracellular fluids in animals and humans. These fluids, such as blood plasma and extracellular fluids in other tissues, bathe cells and carry out transport functions for nutrients and wastes.
Glossary. Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties.
