Transcript : Chemistry in its element: nitrogen Promo You're listening to Chemistry in its element brought to you by Chemistry World , the magazine of the Royal Society of Chemistry.
End promo Chris Smith Hello! Mark Peplow While other scientists had tried to create ways of ordering the known elements, Mendeleev created the system that could predict the existence of elements, not yet discovered.
Chris Smith And you can hear Mark Peplow telling technetium's tale in next week's edition of Chemistry in its element.

Large amounts of ammonia are then used to create fertilizers, explosives and, through a process known as the Ostwald process, nitric acid HNO 3.
Nitrogen gas is largely inert and is used as a protective shield in the semiconductor industry and during certain types of welding and soldering operations. Oil companies use high pressure nitrogen to help force crude oil to the surface. Liquid nitrogen is an inexpensive cryogenic liquid used for refrigeration, preservation of biological samples and for low temperature scientific experimentation.
Jefferson Lab's Frostbite Theater features videos of many basic liquid nitrogen experiments, such as this one:. Hydrogen gas and nitrogen gas reacted via the Haber Process to produce ammonia. This colorless gas with a pungent odor is easily liquefied in fact, the liquid is used as a nitrogen fertilizer. Ammonia is also used in the production of urea, NH 2 CONH 2 , which is used as a fertilizer, used in the plastic industry, and used in the livestock industry as a feed supplement.
Ammonia is often the starting compound for many other nitrogen compounds. Jump to: home search phonebook banner navigation site navigation main content footer navigation. Chemistry Division » Periodic Table of Elements. Back to Elements List In chemistry laboratories, liquid nitrogen is often stored in large thermos-like containers called "dewars. Sources Nitrogen gas N 2 makes up Environmental Protection Agency EPA , nutrient pollution caused by excess nitrogen and phosphorus in the air and water, is one of the most widespread, costly and challenging environmental problems.
One of the solutions to the issue of excessive nitrogen lies in sustainable agriculture, organic farming and raising the awareness of these environmental issues among farmers, according to Randy A. Dahlgren, a professor of soil science at University of California, Davis. Another step would be to use slow-release fertilizers that have plastic coatings on them and, instead of releasing the nitrogen right away, the release of nitrogen occurs gradually throughout the growing season, "trying to match the nitrogen release from the plastic coated fertilizer with the needs of the plant," he said.
Microbiologists at the University of Alberta in Canada and the University of Vienna in Austria may have discovered another solution. In August , the researchers announced they had identified an ammonia-oxidizing microbe called Nitrospira inopinata.
According to the researchers, Nitrospira inopinata is an ammonium sponge, essentially outperforming nearly every other type of bacteria and archaea single-celled organisms in the oxidation of ammonium in the environment.
Because this microbe is such an efficient oxidizer, it may produce less nitrous oxide in the process. The new findings, which appear in the scientific journal Nature , could have important implications for climate change research.
