It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2). Sodium has two radioactive cosmogenic isotopes ( 22. Na, with a half-life of 2.6019 (6) years; [nb 1] and 24. Na, with a half-life of 14.9560 (15) h ). With the exception of those two isotopes, all other isotopes have half-lives under a minute, most ...
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.
Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Davy isolated sodium metal a few days after potassium, by using electrolysis on sodium hydroxide [61] and potash [62] respectively. 19 Potassium: 1702 G. E. Stahl 1807 H. Davy 27 Cobalt: 1735 G. Brandt: 1735: G. Brandt: Proved that the blue color of glass is due to a new kind of metal and not bismuth as thought previously. [63] 20 Calcium: 1739 ...
Sodium hypochlorite is an alkaline inorganic chemical compound with the formula Na O Cl (also written as NaClO). It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. [4] It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −

Sodium was a massively multiplayer online game that was based in and exclusive to the PlayStation 3 's online community-based social gaming network PlayStation Home. Sodium was a planned four-part series of games, only two of which were released by the time of Home's closure.
Voltage-gated sodium channels ( VGSCs ), also known as voltage-dependent sodium channels ( VDSCs ), are a group of voltage-gated ion channels found in the membrane of excitable cells ( e.g., muscle, glial cells, neurons, etc.) with a permeability to the sodium ion Na +. They are the main channels involved in action potential of excitable cells.
