![]() ![]() It is only essential for growth of plants due to bacteria and both animals and humans eat plants that is why they contain nitrogen. None have the ability of fixing the nitrogen all are dependent to soil of the trees to carry this process. They took all the nitrogen from the roots of trees where they live and act as host and transform them to nitrates. Nitrogen is a chemical element with the symbol N, the atomic number. Even some bacteria are used for this purpose. The molar mass of nitrogen (N) is approximately 14.01 grams per mole of nitrogen atoms. When Nitrogen is changed to compound nitrogen is known as nitrogen fixation. During the rain nitric acid is mixed with the metals in the earth’s crust and form compounds like nitrates and nitrites etc. Rather than a free nitrogen, nitric oxide is more reactive and it is formed when Oxygen and Nitrogen combines. In 100 liters of water only two liters of nitrogen could be dissolved.Ĭhemical Properties : Nitrogen is an inactive gas and it only react when there is spark of some kind. Determine the number of protons, neutrons, and electrons in an atom. Nitrogen gas is partially soluble in water. Learning Outcomes Define atomic and mass numbers. It becomes a white solid same as now when it freezes. It could be only change to a liquid from a gas in the temperature of -320.42oF and changes to a solid from a liquid in the temperature -346.42oF. Nitrogen (N2) - Nitrogen (N2) Nitrogen is a chemical element that has the symbol N and atomic number 7 and atomic mass 14.00674. Physical Properties: Nitrogen gas is an odorless, colorless and tasteless gas. It can be beneficial or harmful to steels dependent upon its type. In the process of basic oxygen furnace it results to the low amount of nitrogen in the steels while in the Electric arc furnace it results to the higher amount of nitrogen. Some of the examples of nitrogen composition in steel grades are P235GH steel, P265GH and 1.0038 steel. Steel contain nitrogen in the form of impurity. Alloying Behavior of Nitrogen: As an alloying element nitrogen react with steel. ![]()
