What is the molecular formula for nitrogen?
At standard temperature and pressure, two atoms of the element bind to form dinitrogen, a colourless and odorless diatomic gas with the formula N2. Dinitrogen forms about 78% of Earth’s atmosphere, making it the most abundant uncombined element.
What is N2 in nitrogen?
2. Molecular nitrogen (N2) is a relatively inert gas due to the strong triple bond between the two nitrogen atoms. The biological N cycle is largely restricted to molecules in which nitrogen is bound less strongly to elements other than nitrogen.
How many atoms are in a molecule of nitrogen?
Four representations chemists use for nitrogen molecules. Nitrogen is a chemical element with an atomic number of 7 (it has seven protons in its nucleus). Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together.
How many atoms are there in 70 gram of nitrogen?
Therefore, 28 grams of nitrogen =6.023×1023 molecules of nitrogen =2×6.023×1023 atoms of nitrogen, as each molecule of nitrogen has 2 atoms. Therefore 70 gram of nitrogen =2×6.023×1023×7028 atoms of nitrogen = 5×6.023×1023 atoms of nitrogen = 5 times the Avogadro’s number.
