Nitrogen is a chemical element which has the symbol N and atomic number 7 in the periodic table. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.08% percent of Earth's atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen.

Nitrogen is an atom with 7 protons and 7 electrons. Normally when someone refers to a substance they mean the form that is normally found in nature, and nitrogen is normally found as a diatomic molecule and actually the majority of our atmosphere is diatomic nitrogen. It is chemically inert in normal conditions.
