азот

Also known as element 7, N, ₇N

химический элемент с порядковым номером 7

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.

Азо́т (химический символ — N, от лат. Nitrogenium) — химический элемент 15-й группы (по устаревшей классификации — главной подгруппы пятой группы, VA), второго периода периодической системы Д. И. Менделеева, с атомным номером 7. Как простое вещество (при н. у.) азот — двухатомный газ (химическая формула — N2) без цвета, вкуса и запаха. Один из самых распространённых элементов на Земле. Основной компонент воздуха: 78 % объёма. Химически весьма инертен, однако реагирует с комплексными соединениями переходных металлов. Применяется как инертная среда для множества технологических процессов; жидкий азот — хладагент. Азот — один из основных биогенных элементов, входящих в состав белков и нуклеиновых кислот.
