Question

What is the chemical formula for nitrogen?

Answer 1

Hint: The word nitrogen can be seen in two ways:-
-The chemical formula for nitrogen as an element is ‘N’.
-The chemical formula for nitrogen gas is ‘${{N}_{2}}$’.

Complete answer: Nitrogen is a chemical element whose atomic number is 7. It is the lightest member of group 15 of the periodic table which is often called the pnictogens. Nitrogen is a common element in the universe which is estimated to be ${{7}^{th}}$ abundant in the Milky Way galaxy and the Solar System.
-The chemical formula for element Nitrogen is ‘N’.
-At a condition of standard temperature and pressure when two atoms of the same element bind through covalent bonds to form dinitrogen, a colorless and odorless diatomic gas is obtained. Nitrogen gas forms about 78% of Earth's atmosphere which makes it the most abundant uncombined element.
-The chemical formula for nitrogen gas is ‘${{N}_{2}}$’.
-In the case of ${{N}_{2}}$ gas, the two nitrogen atoms are bonded by a triple covalent bond (3 electrons are contributed by each atom to form triple bonds).
-Nitrogen has two stable isotopes: $^{14}N$ and $^{15}N$. The$^{14}N$ is much more common, making up to 99.634% of natural nitrogen, and the $^{15}N$, which is slightly heavier, makes up the remaining 0.366%.

Note: Nitrogen(N) bonds to almost all the elements in the periodic table except for the first three noble gases i.e., helium, neon, and argon and also some of the very short lived elements after bismuth due to which it creates an immense variety of binary compounds with varying properties and applications.
