Some of the interesting fact about this element are:

Fact 1: Nitrogen is colorless, tasteless, and odorless.

Fact 2: Earth’s atmosphere contains 78.1% by volume of nitrogen gas.

Fact 3: Nitrogen gas has a melting point of -346° F and a boiling point of -320.4° F.

Fact 4: Nitrogen is the most common element found in the universe and is about seventh in total abundance both in the Milky Way and the Solar System.

Fact 5: When ionized, nitrogen is passed through a gas discharge tube. It produces a purple glow inside the discharge tube.

Fact 6: Nitrogen exists in all living organisms. Some soil bacteria has the capability of converting nitrogen into a form that can be used by plants and animals to make proteins and amino acids.
