īecause its outer shell comprises five electrons, it is trivalent in most compounds. The molecular weight of nitrogen gas is 28.02 u. Nitrogen has a molar mass of 28.02 g /mol. With an electronegativity 3.04, nitrogen is a nonmetal. We are discussing some properties of nitrogen here. The atomic structure of nitrogen is shown below. So nitrogen gas formula is actually the nitrogen formula. Nitrogen is commonly found as nitrogen gas. A triple bond binds both nitrogen atoms as a molecule of nitrogen gas. Both nitrogen atoms contribute their 3 outer shell electrons to form covalent bonds. That’s why in nature nitrogen is found as nitrogen gas as two nitrogen atoms come together to form a molecule that is more stable than an atom. Due to this half-filled configuration, nitrogen has a valency of 3. Now when we see that the outer p-orbit is half-filled that is comparatively stable than other configurations. The outermost orbit is p and it requires 6 electrons to fill completely. As a result of reactions in the nitrogen cycle, industrial enterprises emit a lot of nitrogen, which increases the amount of nitrite and nitrate in the ground and water.Īs we had seen the electronic configuration of nitrogen gas in the previous section, we can say that nitrogen has 3 electrons in its outermost orbit. It can be found in soil and water as nitrates and nitrites.Īll of these elements are linked and part of the nitrogen cycle. It is a necessary component of life because it is a component of DNA and a part of the genetic code. Most of its compounds are trivalent because its outer shell has five electrons. It is predominantly diatomic non-metal gas, which is odourless and colourless in nature. Nitrogen gas makes up around 80% of the Earth's atmosphere. Nitrogen is the seventh element in the periodic table, located between carbon and oxygen.Įlectronic configuration of nitrogen is \\] 2 s 2 2 p 3. Nitrogen is found as Nitrogen gas in nature and the symbol of nitrogen gas is N 2. Some basic information about Nitrogen are as follows. Nitrogen is the member of the 15th group of the modern periodic table. Nitrogen gas is a colourless, odourless gas that makes up around four-fifths of the atmosphere's volume and is found in mixed form in animal and vegetable cells, particularly proteins. Of course, the "fire air" was oxygen, while the "foul air" was nitrogen. Carl Wilhelm Scheele, a Swedish chemist, demonstrated in 1772 that air is a mixture of two gases, one of which he dubbed "fire air" because it promoted combustion, and the other "foul air" because it remained after the "fire air" had been consumed. Nitrogen makes up around four-fifths of the Earth's atmosphere, and it was isolated and identified as a distinct substance during early air research.
