<h1>
Nitrogen is a chemical element with symbol N and atomic number 7. It is
the lightest pnictogen and at room temperature, it is a transparent,
odorless diatomic gas. Nitrogen is a common element in the universe,
estimated at about seventh in total abundance in the Milky Way and the
Solar System. On Earth, the element forms about 78% of Earth's
atmosphere and as such is the most abundant uncombined element. The
element nitrogen was discovered as a separable component of air, by
Scottish physician Daniel Rutherford, in 1772.
