Molecular formula : MW : CAS :
nature : Periodic System FIRST main ethnic group (base metal) elements. Atomic number 11. Stable isotopes : 23. Amu 22.989770. The silver-white metal. Light, soft and extensible. When the temperature is cereus, low temperature embrittlement. Density 0.97. 97.82 ° C melting point. Boiling Point 882.9 ° C Valence +1. The chemical nature lively, with direct non-metallic compound. The air oxidation speed. Combustion of yellow flame. WATER dramatic role, generating hydrogen and sodium hydroxide. General stored in kerosene. Rockets fired in the atmosphere high sodium vapor can produce bright yellow and orange clouds. TiCl4 reduction can be used to take Ti system. In addition, sodium can be used as organic synthesis and some metal smelting of the reductant, as a catalyst for synthetic rubber, oil desulfurizer, nuclear reactors heat carrier, and for hydrogen Sodium, Na2O2, such as amino sodium. Sodium lamps can be used as a monochromator. A natural rock salt and Trona, water contains a lot of salt. Industrial mainly by the electrolysis of sodium chloride and melting in the system.
