An oxide is a chemical compound containing at least one oxygen atom as well as at least one other element. Most of the Earth's crust consists of oxides. Oxides result when elements are oxidized by oxygen in air. Combustion of hydrocarbons affords the two principal oxides of carbon, carbon monoxide and carbon dioxide. Even materials that are considered to be pure elements often contain a coating of oxides. For example, aluminium foil has a thin skin of Al2O3 that protects the foil from further corrosion. Virtually all elements burn in an atmosphere of oxygen, or an oxygen rich environment. In the presence of water and oxygen (or simply air), some elements - lithium, sodium, potassium, rubidium, caesium, strontium and barium - react rapidly, even dangerously, to give the hydroxides. In part for this reason, alkali and alkaline earth metals are not found in nature in their metallic, i.e., native, form. Caesium is so reactive with oxygen that it is used as a getter in vacuum tubes, and solutions of potassium and sodium, so called NaK are used to deoxygenate and dehydrate some organic solvents. The surface of most metals consists of oxides and hydroxides in the presence of air. A well known example is aluminium foil, which is coated with a thin film of aluminium oxide that passivates the metal, slowing further corrosion. The aluminium oxide layer can be built to greater thickness by the process of electrolytic anodising. Although solid magnesium and aluminium react slowly with oxygen at STP, they, like most metals, will burn in air, generating very high temperatures. As a consequence, finely grained powders of most metals can be dangerously explosive in air. In dry oxygen, iron readily forms iron(II) oxide, but the formation of the hydrated ferric oxides, Fe2O3-2x(OH)x, that mainly comprise rust, typically requires oxygen and water. The production of free oxygen by photosynthetic bacteria some 3.5 billion years ago precipitated iron out of solution in the oceans as Fe2O3 in the economically-important iron ore hematite. Due to its electronegativity, oxygen forms chemical bonds with almost all elements to give the corresponding oxides. So-called noble metals (common examples gold, platinum) resist direct chemical combination with oxygen, and substances like gold(III) oxide must be generated by indirect routes.

2. How the Compass Has Evolved
November 19, 2009
The origins of the modern day compass date back to the 4th century in China. It was first used as a device for guiding people to find corners of austerity in their homes, as pertaining to the ancient art of Feng Shui. The earliest model used lodestones (an iron oxide that aligns itself to the north and south) in a bowl of water to point to the best direction for window, doors and goods to be located in the home. So how did they make the jump from the first model to what we have today? It was discovered in the 12th century by an Englishman that steel needles would hold a ma... (read more)

4. Fashion Jewelry Tell You The History Of Crystal
November 16, 2009
History of crystal dates back thousands of years to the Mesopotamian times. Lead oxide was used to enhance the brilliance of glass as used today, but applied in different way.

13. L-arginine, Nitric oxide and Male Libido
November 05, 2009
Most men are not really aware of this but nitric oxide is an essential chemical that is released in the walls of the blood vessels that facilitate hard and firm erections. When you get sexually excited your brain nerves cause the release of nitric oxide. This chemical helps the penile muscles to relax so that blood vessels can dilate and more blood can flow into the erectile tissue resulting in hard and firm erections. Nitric oxide secretion begins declining with age and this leads to erectile failure in men. The decreased level of nitric oxide causes hardening of arteries which stops the f... (read more)

14. A bit of history related to the discovery of polystyrene
November 03, 2009
History of Polystyrene foam: Polystyrene was accidentally discovered in 1839 by Eduard Simon; an apothecary in Berlin, Germany. From storax, the resin of Liquidambar orientalis, he distilled an oily substance, a monomer that he named styrol. Several days later Simon found that the styrol had thickened, presumably due to oxidation, into a jelly he dubbed styrol oxide ("Styroloxyd"). By 1845 English chemist John Blyth and German chemist August Wilhelm von Hofmann showed that the same transformation of styrol took place in the absence of oxygen. They called their substance metastyrol. Analysis l... (read more)
