When nitrogen gas is formed as a product from various reactions, the bond energy associated with the N-N triple bond is released, causing the explosive properties seen in many nitrogen compounds. These properties are determined by the extremely strong and stable bond found in molecular, diatomic nitrogen, N 2, which has a bond dissociation energy of 945 kJ/mol (226 kcal/mol). Nitrogen compounds play an important role in many aspects of life and commercial processes, from the industrial production of fertilizers to the building blocks of life.
