Nitrogen is a colorless, odorless gas that can be found in group 15 of the periodic table. Nitrogen is represented by the symbol, N, and has an atomic number of 7. This element was discovered by Daniel Rutherford in 1772. Mr. Rutherford studied Edinburgh University where he began his research on this gas. It started with an experiment including a mouse in a small enclosed area, and from there concluded that the air being released by the mouse was what we know as Nitrogen. At room temperature this element is a gas. Nitrogen has an atomic number of 7, and its isotopes number 14. Other important things to note about this element is the electron configuration which is [He]2s^22p^3, as well as its density which numbers 1035 K.
Nitrous oxide, symbolized by N2O is one of the compounds formed by Nitrogen. This compound was discovered in 1776 by Joseph Priestley. This compound is actually a very easy compound to make. It can be made right at your own home. It involves heating ammonium nitrate to a temperature between 170 degrees Celsius and 240 degrees Celsius in which it breaks down into nitrous oxide and water vapor. The formula is noted as “NH4NO3(s)-2H2O(g)+N2O(g)” (How To Make Nitrous Oxide). What you will need for this type of experiment is Ammonium nitrate, a Bunsen burner, nitrous oxide and water vapor, a test tube and test tube cap, a pipe, hot water, sheet metal with ½ inch hole, and a breaker with pure N2O. Another compound formed by this element is nitric oxide symbolized by NO. “…in air it forms nitrogen dioxide, NO2, a poisonous reddish brown gas.” (Encyclopedia2). Nitrogen trioxide symbolized by N2O3 is also a compound formed from Nitrogen as well as Nitrogen pentoxide, N2O5 which creates nitric acid when it is put in wat...

...ontact with water it creates an ammonia gas product. This compound is known to be a catalyst as well as being able to produce “tiny dark lumps” (Magnesium Nitride) that “could scratch a polished block of boron carbide, something only diamond was known to do.” (Magnesium Nitride). Potassium Nitrate or KNO3 is used mostly in the agriculture business to protect chloride free sources such as tobacco, potatoes, and lettuce from deterioration. This compound is also popular among pharmaceutical companies. ‘Its use being to help in the desensitization of sore teeth, and it is commonly used in many toothpaste products.’ (PNA) Sodium nitrate known as NaNO3 is a combination of sodium and nitrogen and is found in a powder like form. This substance is used every day in the use of pesticides and helps in getting rid of insects and pest that could be a threat to important crops.
Neon was discovered in 1898 by British chemists Sir William Ramsay and Morris W. Travers as a component of the most volatile fraction of liquefied crude argon obtained from air. Upon applying an electric current to it, the chemists found that it had an orange glow, and they decided that it was not argon, but rather a new element altogether.
Ammonium nitrate, on its own, is relatively harmless in regards to explosives. Ammonium Nitrate is a secondary explosive; it requires a primary explosive for detonation. It is able to burn without detonating and can withstand shock in which primary explosives are unable to do When ammonium nitrate is mixed with fuel oil and detonated the results can be catastrophic. The Oklahoma City bombing of 1995 is evidence of the impact of a blast using ammonium nitrate and fuel oil, known as ANFO. Timothy McVeigh parked a van filled with ammonium nit...
The major sites for the production of ammonia are the intestines, liver, and kidneys. It is biosynthesized through normal amino acid metabolism. The kidneys generate ammonia from glutamine by the actions of renal glutaminase and glutamate dehydrogenase. Ammonia is formed from urea by the action of bacterial urease in the lumen of the intestine, which is absorbed from the intestine by the portal vein. Amines obtained from diet and monoamines that serve as neurotransmitters or hormones can create ammonia by action of amine oxidase. In purine and pyrimidine catabolism, amino groups attached to the rings are released as ammonia.
Radon is the final element of the noble gases. Its symbol is 86 and its atomic number is 86. It is colorless, tasteless, odorless and a gas. It is one of the densest substances that remains a gas under normal conditions.
A propellant is used in the military application and it is consists of oxidizer, fuel, plasticizer, curing agent and cross linkers. The commonly used oxidizer is ammonium perchlorate. But its combustion products are environmentally hazardous. Nowadays, ammonium nitrate is gaining great attraction in the field of propellant as a great oxidizer. Ammonium nitrate is an inorganic compound used as fertilizer, oxidizer and also for other applications. AN combined with fuel can be used in gas generators . The ammonium nitrate extracted from demilitarized rocket motors can be used as an oxidizing agent in the hydrothermal oxidation of organic wastes . It has seven phase transitions3.

It is stable and incompatible with moisture and acids.Potassium carbonate is used in pharmaceutical labs to help aid in the drying process. Potassium Nitrate ( KNO3) has an average mass of 101.103 Da with a colorless crystal appearance or in white powder form. It is soluble in water, glycerol, and liquid NH3. It is stable and a strong oxidizer that has a melting point at 334 degrees celsius.Potassium nitrate is found in fertilizers, gunpowder, and in fireworks. Potassium hydrogen carbonate ( KHCO3 ) has an average mass of 100.115 Da and is stable. It also has a white powder or crystal appearance with a melting point at 100 degrees
Every chemical element or compound have specific properties that make them different than the other. However, these properties help us to understand every element or compound in which they can be used and how we can deal with them. These properties can be chemical properties which are defined as "that property must lead to a change in the substances ' chemical structure", such as heat of combustion and flammability ("Physical and Chemical…"). Also, these properties can be physical properties which are defined as the properties "that can be measured or observed without changing the chemical nature of the substance", such as mass, volume, boiling and freezing points ("Physical and Chemical…"). These two properties are related to each other. For
Nitrogen can be considered as both a fertilizer and nutrient under the right constraints. I will use citrus plants as one of my examples. For citrus growers applying nitrogen to plants is a common and needed practice. “Spring is the best time to apply nitrogen to citrus. Research has shown that the demand for nitrogen in citrus is highest from bloom through June and most of the supplemental nitrogen fertilizer should be applied during this time period.” It is a major key to plant growth and development. Nitrogen is crucial to citrus plants for optimal growth and yield. Without nitrogen you can see suffering results for many years down the road.
nucleation. When nucleation in the liquid phase is catalyzed by foreign surfaces other than the material to be crystallized (such as by dust particles or wall surfaces), it is described as primary heterogeneous nucleation. In solutions in which crystals already exist, secondary nucleation is thought to be by far the most significant source of nuclei. The supersaturation at which secondary nucleation rises is much lower than that which gives rise to primary nucleation.( Garside and Davey ,1980; Garside, 1985; Nyvlt et al., 1985); Fig. (I.4) shown A simple scheme for nucleation .
In 1937, technetium-99m was discovered by C. Perrier and E. Segre. It is a radionuclide, and was first discovered as an artificial element that was used to fill space number 43 in the periodic table. 1
Gasoline, nail polish remover, felt-tip markers, and glue contain volatile solvents. Sprays that contain propellants and solvents fall under the aerosol category. Paint, deodorant, cooking products, and silver and gold spray paint are familiar aerosols. Substances that lack definite shape or volume such as refrigerants and medical anesthetics are gases. Nitrous oxide, also known as laughing gas, is abused more often than any gas. It can be obtained from whipped cream dispensers, products that boost octane levels in racing cars, balloons, or small sealed vials called whippets. Gases found in butane lighters, air c...
Looking closely to the three chemicals: nitrogen is considered the most important substance of a fertilizer, it contribute to the greening of the leaves and their growth. Phosphorous’ job is to enhance the growth of roots, seeds and flowers. Fertilisers with high percentage of phosphorous can benefit on solid root system. Finally potassium is essential to fruit and vegetables’ plants, it helps the organism to resist against diseases.
Nitrogen containing flame retardants release stable and inert compounds like nitrogen gases which stop the fire cycle by either interfering with the flammable gases or with the thermal degradation of the burning material. Nitrogen containing FRs can also enhance the performance of phosphorus FRs when
These are some of the many properties reasons and qualifications for us using sodium in our everyday lives. These are the reasons why sodium is used all around the world to this very day and is also why we use so much of it. Ammonia has an important role in the formation of salt crystallizations which is why it is mentioned in the above paragraph and which so will be used in the experiment that is going to take place to test the importance of ammonia in salt crystallization and to see exactly how the ammonia is going to affect the salt in the end result.
