Sodium

Positive Attributes: Metallic sodium is vital in the manufacture of esters and in the preparation of organic compounds. The metal may also be used to improve the structure of certain alloys.Negative Attributes: Sodium is potentially explosive in water (depending on quantity) and is a caustic poison, since it is rapidly converted to Sodium Hydroxide on contact with moisture. Compounds: 1.) Sodium Chloride makes common table salt2.) Soda Ash is made up of sodium, carbon, and oxygen.3.) Baking Soda is made up of hydrogen, sodium, carbon, and oxygen. Chemical Description:Valence Electrons: One Ion: Na+1 Oxidation Number: +1Reactivity: Very Reactive
