What is the formula for nitrogen?

Nitrogen is one of the base elements found on the periodic table and is designated by the chemical symbol N. In nature, two N atoms are generally found paired up to form an N2 molecule, which exists as a colorless, odorless and tasteless gas, according to the Encyclopedia Britannica.

Nitrogen is atomic number 7, which means it is made up of 7 protons and 7 electrons. It is the most abundant element in the Earth's atmosphere, taking up around 78 percent by volume of dry air. The Random House Dictionary lists ammonia, cyanide, fertilizer, dyes and cooling agents as common substances made from nitrogen.
