Group 1 and Group 2 elements are collectively called as s-block elements. Se hela listan på periodic-table.com Sodium (atomic number 11, symbol Na) is a metal and a chemical element that was discovered in 1807 by the Cornish inventor and chemist Humphry Davy. It occurs in sodium salts and minerals, including rock salt, sodalite, and feldspars. The chemical symbol for Sodium is Na. Sodium 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 that it readily donates, creating a positively charged atom—the Na+ cation.
