Discovery of Nitrogen
Nitrogen, atomic number 7, has a mass of 14.007 au.
Nitrogen exists as a diatomic molecular gas, N2, and in this form it makes up about 78% of the atmosphere by volume. The element seemed so inert that Lavoisier named it azote, meaning "without life".
Nitrogen was first isolated in 1772 by D. Rutherford.
