  Inorganic chemistry - Wikipedia, the free encyclopedia
Inorganic chemistry is the branch of chemistry concerned with the properties and reactions of inorganic compounds.
Inorganic chemistry is based upon physical chemistry and forms the basis for mineralogy and materials chemistry.
The range of inorganic chemistry includes both molecular compounds, which exist as discrete molecules, and crystals, whose structures are described by infinite lattices of regularly-ordered atoms and which are studied by crystallography and solid-state chemistry.

Inorganic chemistry is the branch of chemistry concerned with the study of materials that contain any combination of chemical elements except for organic compounds.
Inorganic chemistry often overlaps with mineralogy, geochemistry,analytical chemistry, environmental chemistry, physical chemistry, and organometallic chemistry.
Organometallic chemistry combines aspects 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.

 Mercury, inorganic (EHC 118, 1991)
Inorganic mercury compounds are probably absorbed from the human gastrointestinal tract to a level of less than 10% on average, but there is considerable individual variation.
Exposure to inorganic mercury from dental fillings could explain the high proportion of inor- ganic mercury in the Swedish study but not in the Japanese study, as it seems reasonable to assume that the mercury exposure from amalgam should be approximately the same in the two countries.
Inorganic mer- cury has been reported to have effects at concentrations of the metal in the culture medium of 5 µg/litre, and organomercury compounds at concentrations at least 10 times lower than this.

 EPA - Air Toxics Website - Arsenic Compounds
Inorganic arsenic exposure in humans, by the inhalation route, has been shown to be strongly associated with lung cancer, while ingestion of inorganic arsenic in humans has been linked to a form of skin cancer and also to bladder, liver, and lung cancer.
Inorganic arsenic is still used as an antiparasitic agent in veterinary medicine and in homeopathic and folk remedies in the United States and other countries.
Inorganic arsenic is found throughout the environment; it is released into the air by volcanoes, the weathering of arsenic-containing minerals and ores, and by commercial or industrial processes.

 Minerals
Inorganic minerals are referred to as salts or mineral salts.
The inorganic chemicals like chlorine, alum and sodium fluoride are inert, which means that they cannot be absorbed into the living tissues of the body.
Consequently, the inorganic salts (inorganic minerals) are stored and in time take their toll in the form of hardening of the arteries, stones within the kidneys, urethras, gall bladder, joints and an etiologic factor in enlargement of the adipose cell (fat cell).

 Inorganic Chemicals
Inorganic chemicals are elements or compounds found in water supplies.
In larger amounts, however, inorganic chemicals can be dangerous and can cause a variety of damaging effects to the liver, kidney, nervous system, circulatory system, gastrointestinal system, bones, and skin, depending upon the chemicals and level of exposure.
The inorganic chemical regulations allow public water systems to obtain waivers from the monitoring requirements (except for nitrate and nitrite, which cannot be waived).

 Inorganic Chemistry
Regarding the importance of inorganic chemistry, R.T. Sanderson has written: "All chemistry is the science of atoms, involving an understanding of why they possess certain characteristic qualities and why these qualities dictate the behavior of atoms when they come together.
Inorganic chemistry (is) the only discipline within the chemistry that examines specifically the differences among all the different kinds of atoms".

Even with a prior inorganic course, the novel approach taken in many of the chapters is almost certain to be quite different from what students have previously seen and will require extra time to cover.
Because of the greater coverage and somewhat higher level of Inorganic Chemistry, this approach would be more challenging for students than using PDIC in the introductory course but would have the advantage of requiring the purchase of only one text.
Inorganic Chemistry is an interesting new option for teachers of advanced inorganic courses and offers the possibility of serving an introductory course as well.

 Amazon.ca: Books: Instant Notes in Inorganic Chemistry   (Site not responding. Last check: 2007-11-07)
Inorganic chemistry can claim to be a peculiarly broad subject, dealing with the descriptive chemistry of all the elements, together with some general principles which provide a framework and enable the detailed facts to be seen in context.
Part of the interest in inorganic chemistry lies in its relevance in the world outside the laboratory, including environmental, biological and industrial areas, so the book includes brief mentions of these aspects under individual elements, and also as separate topics in the final section.
If you are studying inorganic chemistry and need an easy to understand text "Instant Notes in Inorganic Chemistry" is the lifeline you need to help you understand the subject.

 Re: what is the difference detween an inorganic and organic compound?
Inorganic compounds are produced by non-living natural processes or by human intervention in the laboratory.
Not only are there plenty of inorganic compounds that don't form salts (for example, sulfur hexafluoride SF), but there are a number of organic compounds that do form salts: not only carboxylic acids but amines, alcohols, and even acetylene can form salts.
Normally organic chemists study organic or organometallic compounds, and inorganic chemists study organometallic compounds or inorganic compounds.
