Sodium - Wikipedia

Sodium is a chemical element with the syol Na (from Latin natrium) and atomic nuer 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na + ion.
