Etymology

Description

It is a colorless and gaseous element in group 15 of the periodic table. It makes up about 78% of the atmosphere and is an important part of the ecosystem. Nitrogen used for industrial purposes is obtained by fractional distillation of liquid air. It is chemically inert and reacts only at high temperature or during electrical discharge. It was discovered by D. Rutherford in 1772.

Language Of Origin

Greek through Latin and French

Origin Of Word

From the combination of the Greek word nitron and the suffix -gen. It means "nitrate forming".

Meaning

nitrate making

Symbol Origin

descriptive

Etymological Description

The English name of the element, nitrogen, comes from the French "nitrogène", which derives from the Greek expression nitron geinomai, meaning "I make nitre". At the same time, the Andalusian Arabic expression Azot, which comes from the Classical Arabic name of the element, al-zuk, was also used.
