Nitrogen (atomic number 7, symbol N) is a tasteless, odorless, and colorless chemical element, which, by volume, constitutes 78.09 percent of the earth's atmosphere. According to estimates, this element is 7th in abundance in the solar system and our galaxy. Scientists hypothesize that its occurrence is the result of a fusion reaction between hydrogen and carbon in supernovas. While nitrogen is a volatile element, its compounds occur commonly in the form of gases on Earth and in the atmospheres of moons and planets with atmospheres.
A number of industrially important compounds contain nitrogen, including organic nitrates (e.g. explosives and...Read More
