Etymology of NITROGEN
The word "nitrogen" originates from the Latin word "nitrogenium", which was coined by French chemist Jean-Antoine Chaptal in 1790. The term is a combination of the Latin word "nitrum", meaning "nitrate" or "saltpeter", and the Greek word "genes", meaning "forming" or "producing". Therefore, "nitrogenium" can be roughly translated as "nitrate-forming" or "nitrate-producing". The name was given to reflect nitrogen's role in the formation of nitric acid and nitrates.
