About Sodium

Sodium Bohr

Similar to the other members of the alkali metal family, sodium is a silvery-white conductive metal that is soft enough to be cut with a knife. Though less reactive than potassium, sodium metal rapidly oxidizes in contact with air and will ignite, releasing pure hydrogen and caustic sodium hydroxide, upon contact with water. Its low density allows the metal to float on water, a property that only potassium and lithium share. Sodium is the most commercially important alkali metal and the 6th most abundant element on earth; it has one stable isotope (23Na) and is present in underground salt mines, seawater, and numerous minerals such as cryolite, feldspars, sodalite, halite, natron, and zeolites. Metallic sodium is typically produced via electrolysis of a molten mixture of sodium chloride and calcium chloride in an electrochemical apparatus known as a Down’s cell.

Sir Humphry Davy first isolated the element in 1807 via electrolysis of sodium hydroxide, the same method that he had used several months earlier to isolate potassium for the first time. The element’s name comes from the common name for sodium carbonate, “soda,” from the Arabic suda or Latin sodanum, all meaning “headache;” as the headache-relieving properties of the compound had long been known. The Latin term for the compound, natrium, served as the basis for the sodium’s elemental symbol of Na.

Sodium has a vast range of applications and uses in the industrial, biomedical, and chemical fields. Metallic sodium is used primarily in chemical reactions to product organic esters and compounds such as sodium azide, indigo, and triphenylphosphine. It is often used in nuclear reactors because of its low boiling point. The vibrant yellow-orange flame caused by burning sodium gives street lamps their distinct color. Its compounds are highly soluble and often used in soaps, glass products, papers, and textiles; sodium chloride is a common de-icing agent, as well as what is commonly known as table salt. The element is biologically important to the function of most systems in the human body, and is common in food additives and pharmaceuticals.

Sodium can be used to improve the structural properties of certain alloys such as aluminum silicon and tin nickel copper; sodium potassium alloy (NaK) is particularly effective as a heat transfer medium and a dessicant, and a sodium, potassium, and cesium alloy (Na 12%/K 47%/Cs 41%) has the lowest melting point of any known alloy. Other uses for sodium have emerged in the fields of high technology electronics and optics: sodium yttrium fluoride (NaYF) is a luminescent phosphor nanocrystal for LEDs, sodium bismuthate has been studied as an analog to 3D graphene, and sodium-air batteries are a promising next-generation green storage medium with the potential to be a viable alternative to the current prevailing lithium-ion battery technology.

High Purity Sodium Chloride Sodium is primarily used in its metallic form in the production of chemical esters and in the manufacturing of various other organic High Purity (99.999%) Dodium Oxide (NaO<sub>2</sub>)Powder compounds. The metal is used in the alloy of tin, nickel and copper for its structural characteristics. Sodium compounds are also used in low tech applications throughout industry. Elemental or metallic forms of sodium include cubes, ingots, lumps, and sticks for evaporation source material purposes. Sodium oxides is available in powder and dense pellet forms for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Sodium fluorides is another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Sodium is available in soluble forms including chlorides, nitrates and acetates. These compounds are also manufactured as solutions at specified stoichiometries.

Sodium Properties

Sodium Bohr Model
Sodium is a Block D, Group 5, Period 4 element. The number of electrons in each of Sodium's shells is 2, 8, 1 and its electron configuration is [Ne] 3s1. The sodium atom has a radius of 185.8.pm and it's Van der Waals radius is 227.pm. In its elemental form, CAS 7440-23-5, sodium has a silvery white metallic appearance. Sodium was first discovered by Sir Humphrey Davy in 1807. It is the sixth most abundant element making up 2.6 % of the earth's crust. Sodium does not occur in nature and must be extracted from its compounds. The name sodium comes from the Latin word "natrium" which means sodium carbonate. Sodium information, including technical data, safety data, high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on earth, conductivity and thermal properties are also included.
