OverviewAI-generated

Nitrogen is a chemical element with the symbol N and atomic number 7. It is classified as a nonmetal and an atmophile element. The element was discovered in 1772 in the United Kingdom by Daniel Rutherford. Its name is derived from nitre and life.

Nitrogen has an atomic mass of 14.007 and an electronegativity of 3. Its electron configuration is 1s² 2s² 2p³. It is part of period 2 and group 15, and its chemical formula is N₂. The element exhibits oxidation states of -3, -2, -1, and 1. It is used as a food additive.

窒素（ちっそ、英: nitrogen、仏: azote、独: Stickstoff）は、原子番号7の元素である。元素記号はN。原子量は14.007。第15族元素、第2周期元素。地球の大気中に安定した気体として存在するほか、生物に欠かせないアミノ酸、アンモニアなど様々な化合物を構成する。ハーバー・ボッシュ法によりアンモニアの量産が可能になって以降、人間により工業的に産生された窒素肥料や窒素酸化物が大量に投入・排出され、自然環境にも大きな影響を与えている。一般に「窒素」という場合は、窒素の単体である窒素分子（）を指すことが多く、本項でもそのように用いられる場合がある。本項では窒素分子についても記載する。
