Fertilizer component. Nitrogen was discovered in 1772 by chemist and physician Daniel Rutherford, when the scientist removed oxygen and carbon dioxide from air, demonstrating that the residual gas would support living organisms or combustion, according to the Los Alamos National Laboratory.  Nitrogen is a tasteless, colorless, odorless gas and chemical element. Its chemical symbol is N and atomic number is 7. It is a nonflammable gas found in the earth’s atmosphere. It was discovered by the Scottish physician and chemist Daniel Rutherford in 1772. He discovered this gas by removing oxygen and carbon dioxide from the air. Nitrogen was discovered by Daniel Rutherford in 1772, who called it noxious air, but Scheele, Cavendish, Priestley, and others at about the same time studied burnt or dephlogisticated air, as air without oxygen was then called. Nitrogen: historical information. 1  Discoveror: Daniel Rutherford. 2  Place of discovery: Scotland. 3  Date of discovery: 1772. 4  Origin of name: from the Greek words  nitron genes  meaning  nitre  and  forming  and the Latin word  nitrum  (nitre is a common name for potassium nitrate, KNO#). Rutherford discovered nitrogen by the isolation of the particle in 1772. When Joseph Black was studying the properties of carbon dioxide, he found that a candle would not burn in it. Black turned this problem over to his student at the time, Rutherford. The son of Professor John Rutherford (1695–1779) and Anne Mackay, Daniel Rutherford was born in Edinburgh on 3 November 1749. He left home at the age of 16 to go to college. He was educated at Mundell's School and Edinburgh University (MD 1772). Nitrogen is pronounced as NYE-treh-gen. History and Uses: Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas. Large amounts of ammonia are then used to create fertilizers, explosives and, through a process known as the Ostwald process, nitric acid (HNO 3). Nitrogen gas is largely inert and is used as a protective shield in the semiconductor industry and during certain types of welding and soldering operations. (L. nitrum, Gr. Nitron, native soda; genes, forming) Nitrogen was discovered by chemist and physician Daniel Rutherford in 1772. He removed oxygen and carbon dioxide from air and showed that the residual gas would not support combustion or living organisms.  Nitrogen was isolated by the British physician Daniel Rutherford in 1772, but was not recognized as an element until 1776 by the French chemist Antoine Laurent Lavoisier.  01 Apr, 2008 Who discovered 0. Nitrogen is a chemical element with the symbol N and has an atomic number of 7. Nitrogen is a very important element for organisms and in industry. Nitrogen is a very important part of amino acids and nucleic acids (DNA and RNA).
