Which element corresponds to the symbol N?

The element that corresponds to the symbol N is nitrogen. In the periodic table, each chemical element is represented by a unique one- or two-letter symbol. Nitrogen has the atomic number 7 and is a vital component of the Earth's atmosphere, making up about 78% of it. It is essential for the formation of amino acids and nucleic acids, which are fundamental to life. This element is characterized by its diatomic molecular form (N₂) in its gaseous state and plays a key role in various biological and chemical processes, including the nitrogen cycle.

The other options represent different elements: oxygen is denoted by the symbol O, carbon by C, and phosphorus by P. Each of these elements has distinct properties and uses, but none share the symbol N.
