Hydroxide Formula Diagram (-OH)Sodium Hydroxide, Anhydrous is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Hydroxide, the OH- anion composed of an oxygen atom bonded to a hydrogen atom, is commonly present in nature and is one of the most widely studied molecules in physical chemistry. Hydroxide compounds have diverse properties and uses, from base catalysis to detection of carbon dioxide. In a watershed 2013 experiment, scientists at JILA (the Joint Institute for Laboratory Astrophysics) achieved evaporative cooling of compounds for the first time using hydroxide molecules, a discovery that may lead to new methods of controlling chemical reactions and could impact a range of disciplines, including atmospheric science and energy production technologies. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Sodium Bohr ModelSodium (Na) atomic and molecular weight, atomic number and elemental symbolSodium (atomic symbol: Na, atomic number: 11) is a Block D, Group 5, Period 4 element with na atomic weight of 22.989769. 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 a Van der Waals radius of 227 pm. Sodium was discovered and first isolated by Sir Humphrey Davy in 1807. In its elemental form, sodium has a silvery-white metallic appearance. It is the sixth most abundant element, making up 2.6 % of the earth's crust. Sodium does not occur in nature as a free element and must be extracted from its compounds (e.g., feldspars, sodalite, and rock salt). The name Sodium is thought to come from the Arabic word "suda," meaning "headache" (due to sodium carbonate's headache-alleviating properties), and its elemental symbol Na comes from "natrium," its Latin name.
