Here is some essential information about it:
* Symbol: N
* Atomic Number: 7
* Atomic Mass: \approx 14.007 u
* Classification: Nonmetal, a member of Group 15 (the Pnictogens).
* State at Standard Temperature and Pressure (STP): Gas (as the diatomic molecule, \text{N}_2).
Nitrogen is a largely inert gas and makes up approximately 78% of Earth's atmosphere by volume. It is a critical component of amino acids (the building blocks of proteins) and nucleic acids (like DNA and RNA), making it essential for all life.
