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

Apr 13, 2023 · Sodium is an alkali metal, with atomic number 11 in Group 1 [Ia] of the periodic table. Sodium (from the Latin natrium) is represented in chemical notation by the symbol Na.

The symbol Na derives from the Latin natrium for "natron" (soda in English). Sodium was discovered in 1807 by the English chemist Humphry Davy from electrolysis of caustic soda (NaOH).

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. The atomic mass of sodium is 22.9898.
