Nitrogen is not a noble gas.
Which Elements Are Noble Gases?
The seven elements considered to be noble gases are helium, neon, argon, xenon, krypton, radon and the unnamed Element 118. The noble gases are labeled as Group 18 of the periodic table, and are referred to as “noble gases” because they were thought to be non-reactive elements when first discovered.
What Are the Noble Gases?
Noble gases possess atomic configurations that cause them to be less reactive than most other elements, but they do react to form compounds on rare occasions. Noble gases are odorless, colorless, exhibit fluorescent properties and conduct electricity. Noble gases occur naturally in air but at very low concentrations.
What Is Nitrogen?
Nitrogen is a non-metallic element in Group 15 of the periodic table. It does possess some of the same properties as the noble gases; it is a gas that is odorless and colorless, and it does fluoresce. Unlike the noble gases, nitrogen does not conduct electricity. Although nitrogen is a very stable element, the free electrons in its outer shell mean it reacts with other elements much more readily than the noble gases. Nitrogen is found in ammonia, nitrous oxide, cyanide and many organic compounds. Nitrogen also occurs in the atmosphere in much larger concentrations than the noble gases.
