Inorganic chemistry

Inorganic chemistry is the branch of chemistry concerned with the study of molecules that contain any combination of chemical elements except for organic compounds. Major branches include:

• Minerals, like salt, asbestos, silicates?, chlorine gas, ...
• Metals, like iron, copper, aluminum, brass, bronze, ...
• Non-metallic compounds, like silicon, phosphorus, ...

Some important inorganic products are [silicon chips]?, transistors, LCD screens, and [fiber optics]?.

Inorganic chemistry often overlaps with analytical chemistry, environmental chemistry, physical chemistry, and Organometallic chemistry. Organometallic chemistry combines of organic chemistry with inorganic chemistry, and is partially characterized by the study of metal-carbon bonds, in which the carbon, apart from the metal-carbon bond, would otherwise be considered a part of an organic compound. Vitamin B12, whose active site is similar to that of hemoglobin, is a naturally-occurring, metabolically-important organometallic compound containing a large organic components (porphyrin and protein), a metal (cobalt), a bond between the metal and the carbon of a methyl group. Despite the presence of metal ions or metal-carbon bonds, gold cyanide, calcium carbonate, and nickel tetracarbonyl (to name just a few such) are inorganic, rather than organometallic, compounds.

Adding to the confusion, the oxides of carbon, carbonate salts, and materials containing carbon like steel and diamond are usually considered inorganic, while the inorganic molecule [nitric oxide]? is often studied for biochemical effects.

While inorganic chemistry deals with these on a molecular level, the study of these materials in bulk is called materials science.

This is a page about balloons There is a long history of balloons in and out of the architectural discourse. First, there were the greek balloons which appeared on the Aegean Penninsula around the 5th c. b.c. These were generally depicted in the friezes of the emporer's palace hanging around the ankles of the enemies of the empire.

Later, around 1905, balloons made a resurgence among the clown of Coney Island. There has never been a direct connection made between the original balloons in Greece and these "neo-balloons" in NYC, but it has become the generally accepted hypothesis that a little person, Samuel Frisk who worked at the firehouse in Lilliputia saw the balloons on a visit to Southern Europe looking for a new act. He later came to be known as 'Wild Sam' as he would twist and tie balloons into shapes resembling other "little people."
