Nitrogen (pronounced /'na?t????n/) is a chemical element that has the symbol N and atomic number 7 and atomic weight 14.00674µ. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78% by volume of Earth's atmosphere. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen. The very strong bond in elemental nitrogen dominates nitrogen chemistry, causing difficulty for both organisms and industry in converting the N2 into useful compounds, and releasing large amounts of energy when these compounds burn or decay back into nitrogen gas. The element nitrogen was discovered by Daniel Rutherford, a Scottish physician in 1772. Nitrogen occurs in all living organisms—it is a constituent element of amino acids and thus of proteins, and of nucleic acids (DNA and RNA); resides in the chemical structure of almost all neurotransmitters; and is a defining component of alkaloids, biological molecules produced by many organisms. Nitrogen (Latin nitrogenium, where nitrum (from Greek nitron) means "saltpetre" (see nitre), and genes means "forming") is formally considered to have been discovered by Daniel Rutherford in 1772, who called it noxious air or fixed air. That there was a fraction of air that did not support combustion was well known to the late 18th century chemist. Nitrogen was also studied at about the same time by Carl Wilhelm Scheele, Henry Cavendish, and Joseph Priestley, who referred to it as burnt air or phlogisticated air. Nitrogen gas was inert enough that Antoine Lavoisier referred to it as "mephetic air" or azote, from the Greek word a??t?? meaning "lifeless". Animals died in it, and it was the principal component of air in which animals had suffocated and flames had burned to extinction. Lavoisier's name for nitrogen still remains in the common names of many compounds, such as hydrazine and compounds of the azide ion. Compounds of nitrogen were known in the Middle Ages. The alchemists knew nitric acid as aqua fortis (strong water). The mixture of nitric and hydrochloric acids was known as aqua regia (royal water), celebrated for its ability to dissolve gold (the king of metals). The earliest military, industrial and agricultural applications of nitrogen compounds involved uses of saltpeter (sodium nitrate or potassium nitrate), notably in gunpowder, and much later, as fertilizer.

If you've never heard of a "positive nitrogen balance" and are wondering what the hell I'm talking about don't feel bad, you're not alone. The term isn't something you hear every other guy in the gym talking about. But I can guarantee that even though he may not be familiar with the term, every gym rat on the planet knows what happens when you have a positive nitrogen balance-you get big.
The whole thing is pretty complicated but can be explained fairly simply. Nitrogen is a chemical element found in protein, which we know is the primary building block for muscle growth. And in order to p... (read more)

3. Everything You Need to Know About Orchid Fertilizer
November 17, 2008
Orchid fertilizer is essential for keeping your plant thriving. It delivers a blend of nutrients that the plant converts into energy for development and growth. If you're unfamiliar with the basics of using fertilizer, this article will tell you everything you need to know.
Macronutrients
Every good fertilizer contains three important macronutrients. They include nitrogen, phosphorous, and potassium. This is commonly abbreviated NPK. Nitrogen mainly helps the plant's stem and leaves grow. While growth will likely be restricted if the plant doesn't get enough nitrogen, too much can re... (read more)

4. A New Greenhouse Gas in Town
November 03, 2008
Move Over Carbon Dioxide - There's a New Greenhouse Gas In Town
As we know, carbon dioxide is public enemy number one on the list of deadly greenhouse gases. But there's a new gas in town we must keep a watchful eye on. The name of the gas is nitrogen trifluoride. And actually, it’s not really new. We just underestimated how potent it really was.
The techniques formerly used to measure this gas in our atmosphere provided us with inaccurate numbers. Nitrogen trifluoride emissions are not covered in the Kyoto Protocol of 1997 because it was believed that emissions were not significan... (read more)

October 24, 2008
by Dorothy Yamich
Travelers can save money on gasoline by replacing the air in their vehicle's and RV's tires with nitrogen gas. They can also save money on gas in their every day driving as well. Research has shown that drivers can improve their gas mileage by over three percent when they use nitrogen in their vehicle's tires..
This is not a new technology as it has been used for many years by commercial airlines as well as in NASCAR cars.The Federal Aviation Administration (FAA) mandates that nitrogen gas be used in all commercial aircraft tires to eliminate the possibility of wat... (read more)

6. Vehicle Modification and Fuel Saving Tips
September 29, 2008
Many of our modern automobile makes have been proven fuel efficient, with these vehicles engineered to solve the problems discovered in past models. However, even old vehicles can still be classified among the numerous fuel saving cars in the industry. One way to do that is by modifying these vehicles with the use of fuel saving devices and elements like electronic ignition systems, fuel catalysts, free-flow air filters, nitrogen gas for tire inflation, and other fuel and lubricating oil additives that can lower engine friction and improve combustion.
Some old vehicle models are still eq... (read more)

12. Color Grading Scale
August 26, 2008
Diamonds come in virtually all colors of the rainbow, from the "beautiful violet" of the Hope diamond to shades of blue, brown, gray, orange, etc. But colored diamonds are very rare and precious. Chances are, all the diamonds you'll see in your diamond shopping will be white or yellow, and the whiter the better.
The yellow color in diamonds comes from nitrogen, and as a rule, the more yellow the stone, the less value it has. There's a good reason for this. The yellowier the stone, the less sharp and sparkly it appears. A whiter stone lets lighter pass through it, making it sparkle and shi... (read more)

14. Bodybuilding: Nitric Oxide - NO - NO2
July 15, 2008
Nitric Oxide is a free form gas that is produced in the body and is used by the body to communicate with other cells in the body. To produce this gas, enzymes in the body break down the amino acid Arginine.
Nitric Oxide is a molecule consisting of one atom of nitrogen and one atom of oxygen. The production of Nitric Oxide occurs when the amino acid L-arginine is converted into L-citruline through an enzyme group known as Nitric Oxide Synthase (NOS). The chemical process of conversion is shown in figure 1.

19. Aquarium Care Guide- New Tanks
June 08, 2008
When starting a new aquarium it is important to understand the nitrogen cycle. Many new aquarium owners jump into the hobby of fish keeping too quickly. Before purchasing fish, the aquarium must be cycled. This could take anywhere from twenty four hours to four weeks. In an established aquarium there are certain bacteria that help the breakdown of ammonia to nitrates, but they are not present in a new tank because they are generated from existing fish. If there are no existing fish, then there are no good bacteria.
The basic principle of the nitrogen cycle is this. Fish eat food and gene... (read more)

20. The Facts About Blue Diamonds
June 02, 2008
Diamonds are composed of carbon atoms that have been subject to extreme pressure and heat. If the diamond contains no impurities then the color will be crystal clear. Nature rarely creates anything that does not have any impurities in it. Most diamonds will contain some amounts of nitrogen atoms. If a few of the millions of carbon atoms have been replaced by nitrogen atoms, then structure of the diamond will not be significantly altered but the clarity will be changed.

Argininosuccinic acidemia (ASA) are a disorder of the urea cycle. Aciduria of Argininosuccinic usually become clearly in the firstly little time of living. An infant with argininosuccinic aciduria may be lacking in energy or unwilling to eat, and have poorly controlled breathing rate or body temperature. In argininosuccinic aciduria, the enzyme that starts a specific reaction within the urea cycle is damaged or missing. The urea cycle cannot proceed normally, and nitrogen accumulates in the bloodstream in the form of ammonia. Mutations in the argininosuccinic acidemia gene cause argininosuccin... (read more)
