Nitrogen, with the chemical symbol N, is a vital element constituting approximately 78% of Earth's atmosphere. It was first discovered in the 18th century by the Scottish physician and chemist Daniel Rutherford, who identified it as "noxious air" devoid of oxygen.
Despite being abundant on Earth, nitrogen exists in its pure form as a colorless and odorless gas. Nitrogen makes up about 2.5% of the Earth's crust, primarily in the form of nitrate and ammonium compounds in the soil.
Exciting applications of nitrogen span various industries. In agriculture, it serves as a fertilizer, while the food industry uses nitrogen for packaging and storing food to preserve freshness. The production of ammonia from nitrogen is crucial for manufacturing fertilizers and other chemical compounds.
In the future, applications of nitrogen could witness further innovative developments. The utilization of nitrogen in energy storage, particularly in the form of liquid or gaseous nitrogen as a potential medium for renewable energy, might gain significance. Nitrogen remains not only a fundamental element for life but also a key player in various industrial and forward-looking technologies.
