Continuation of Why do nitrogen-containing organic compounds give N2 as the combustion product? (comment converted into question)
Nascent state is an obsolete theory in chemistry and is discredited. However, nascent nitrogen is still relevant in metallurgical domain especially in the "nitriding process". Basically, nitriding is a process of diffusing nascent nitrogen into the surface of steel, iron and other metals like chromium, aluminum etc. (since ordinary nitrogen is inert at treatment temperatures in the range of 500-600 °C). Ammonia acts as a source of nascent nitrogen because at treatment temperature, it dissociates into nitrogen and hydrogen which cracks on the metal surface and then diffuses into the metal to form respective metal nitrides which creates high hardness in the surface of the nitrided component. This nitrided layer is called the "white layer".
Question: Why is the term nascent nitrogen still used although the theory has become obsolete? Isn't atomic nitrogen a better term?
