Element Nitrogen - N

Comprehensive data on the chemical element Nitrogen is provided on this page; including scores of properties, element names in many languages, most known nuclides of Nitrogen. How to free up memory on an android phone. Common chemical compounds are also provided for many elements. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one's studies.

Unfortunately, the mass number isn't listed on the Table of Elements. Happily, to find the mass number, all you need to do is round the atomic weight to the nearest whole number. Nitrogen's mass number is 14 since its atomic weight, 14.0067, rounds up to 14. Nitrogen 20 is an isotope of Nitrogen with an atomic weight of 20. The mass number is a.

1. The atomic number of nitrogen is 7. What is the mass number of a nitrogen atom with 6 neutrons? An atom has a mass number of 24 and 13 neutrons. What is the atomic number of this atom? 15+ 12-P3+ 15+ 18-P3-12+ 12-Mg. 12+ 10-Mg2+ 12+ 14-Mg2-Charge of K. 1+ Charge of Ba.
2. The nitrogen rule states that a molecule that has no or even number of nitrogen atoms has an even nominal mass, whereas a molecule that has an odd number of nitrogen atoms has an odd nominal mass.

• Abundance of Nitrogen:

    • Atlantic Suface: 0.00008
    • Atlantic Deep: 0.27

  • Sun (Relative to H=1E¹²): 8.71E+07
• Sources of Nitrogen:

  Nitrogen can be made by liquification and then fractional distillation of the air. It is very easily done commercially. It can also be made by heating NaN3 to 300 degrees C. Annual world wide production is around 44,000,000 tons.

• Uses of Nitrogen:

  Nitrogen has many industrial uses in the gaseous forms, but probably the most interesting is liquid nitrogen, which is extremely cold. Items that must be frozen to extremely low temperatures for preservation are frequently stored in liquid nitrogen. Fertility clinics store sperm, eggs and embryos used to help infertile couples become pregnant in ampoules in liquid nitrogen.Since nitrogen gas is very stable, at standard temperature and pressure, it is used as the air in inert welding atmospheres. Documents, foods and chemicals are sometimes stored in nitrogen to keep them from oxidizing or reacting with air or water.

• Additional Notes:

  Nitrogen in the elemental form was considered to be inert and was even named ozote which refers to the fact that it is not reactive. Of course nitrogen does form compounds, but the gaseous form consists of diamers (2 nitrogens bonded together). The diamer is very stable.

  Nitrogen is a major element in organic compounds, especially proteins. Some nitrogen compounds are highly reactive. Trinitrotoluene is TNT or dynamite. Ammonium Nitrate is a fertilizer, but was used as the major explosive ingredient in the Oklahoma City bombing. Anfo, or Ammonium Nitrate and fuel oil mixture is the primary explosive used in the mining industry because it is inexpensive, easy to manufacture and can be easily manufactured near the mine site thus reducing the risks and expenses related to the transportation of explosives. Nitrates, Nitrites and Azides (all nitrogen compounds are either oxidizers or reactives and will react violently under the right conditions.
