[0002] Nitrogen is a chemical element with the symbol N and atomic number 7. In nature, nitrogen mainly exists in its elemental form, namely nitrogen gas (N2). Nitrogen gas is a colorless, odorless, and chemically inert gas that makes up about 78% of the Earth's atmosphere, making it the most abundant component in the atmosphere.

[0003] In industry, nitrogen has extremely wide applications. It is an important raw material for the production of fertilizers, nitric acid, and explosives, and is of great significance to agricultural production and industrial manufacturing. Furthermore, liquid nitrogen, due to its extremely low temperature, is widely used in freezing, medical, and other fields, such as cryopreservation of biological samples and cryotherapy. Nitrogen compounds are numerous and diverse, not only profoundly impacting human life but also occupying an important position in scientific research.
