Nitrogen first was considered a chemical element by Antoine-Laurent Lavoisier, whose explanation of the role of oxygen in combustion eventually overthrew the phlogiston theory, an erroneous view of combustion that became popular in the early 18th century.
Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time.
Rutherford’s nitrogen experiment and discovery was in the late 1700’s. He performed experiments to prove that he had isolated a new element. Rutherford Suggests the Existence of Nitrogen 200 years ago, a scientist discovered an invisible, odorless, and colorless gas.
Daniel Rutherford FRSE FRCPE FLS FSA (Scot) (3 November 1749 – 15 November 1819) was a Scottish physician, chemist and botanist who is known for the isolation of nitrogen in 1772.
Fritz Haber (born December 9, 1868, Breslau, Silesia, Prussia [now Wroclaw, Poland]—died January 29, 1934, Basel, Switzerland) was a German physical chemist and winner of the 1918 Nobel Prize for Chemistry for his successful work on nitrogen fixation.
discovery of nitrogen. …recognized by a Scottish botanist, Daniel Rutherford (who was the first to publish his findings), by the British chemist Henry Cavendish, and by the British clergyman and scientist Joseph Priestley, who, with Scheele, is given credit for the discovery of oxygen.
Nitrogen was discovered as a novel element by Daniel Rutherford (1722) and he termed it as the noxious air [2]. He found that it was that component of the air that did not support combustion.
Daniel Rutherford discovered nitrogen in 1772. He was a Scottish chemist and a physician with a passion for understanding gases, and he owed his discovery to a mouse. When Rutherford placed the mouse in a sealed, enclosed space, the mouse naturally died when its air ran low. He then attempted to burn a candle in the space.
On November 3, 1749, Scottish physician, chemist and botanist Daniel Rutherford was born. Rutherford was the uncle of famous novelist Sir Walter Scott. But originally, he is most famous for the isolation of nitrogen in 1772.
The crucial experiment in the discovery of nitrogen was when it was realized that there are at least two different kinds of suffocating gases in this mephitic air. This was done by passing the mixture of gases through a solution of alkali, which absorbed the carbon dioxide but left behind the nitrogen gas.
