Sodium is a chemical element; it has symbol Na (from Neo-Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds.

4 天之前 · Sodium also is used as a starting material in the manufacture of sodium hydride (NaH) and sodium borohydride (NaBH 4).In addition, sodium is employed in the production of dyes and dye intermediates, in the synthesis of perfumes, and in a wide variety of organic reductions.

The metal was first isolated in 1807, through the electrolysis of sodium hydroxide by Sir Humphry Davy. In 1809, Ludwig Wilhelm, a German physicist and chemist, proposed the name Natronium for it. Its chemical abbreviation ‘Na’ was published in the system of atomic symbols in 1814 which is derived from its Latin name ‘natrium’ [2]. Sodium
