Definition of nitrogen in English:

nitrogen

noun ˈnʌɪtrədʒ(ə)nˈnaɪtrədʒən

mass noun

The chemical element of atomic number 7, a colourless, odourless unreactive gas that forms about 78 per cent of the earth's atmosphere. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant.

Example sentencesExamples

Origin

Late 18th century: from French nitrogène (see nitre, -gen).

Definition of nitrogen in US English:

nitrogen

nounˈnītrəjənˈnaɪtrədʒən

The chemical element of atomic number 7, a colorless, odorless unreactive gas that forms about 78 percent of the earth's atmosphere. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant.
