Nitrogen is important to the chemical industry. The temperature at which the solid–liquid phase change occurs. High = substitution not possible or very difficult. The dissolved oxygen soon gets used up and the river or lake dies. The name nitrogen was therefore proposed from the observation, again first made by Cavendish that if the gases sparked with oxygen, and then the resulting nitrogen dioxide gases passed through alkali, nitre, otherwise known as saltpetre or potassium nitrate is formed. Large quantities of nitrogen are used in annealing stainless steel and other steel mill products. When he presented the table to the world in 1869, it contained four prominent gaps. Unfortunately, Cavendish didn't publish his findings. Far from destroying life, this azotic compound has been responsible for saving thousands. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Crop yields can be greatly increased by adding chemical fertilisers to the soil, manufactured from ammonia.

The nitrate supply is also replenished by nitrogen-fixing bacteria that ‘fix’ nitrogen directly from the atmosphere. First, determine the fractional percent of each isotope in the substance. This is where the artist explains his interpretation of the element and the science behind the picture. The other elements in its group, phosphorus, arsenic, antimony and bismuth, had all been discovered, used and abused at least 100 years before nitrogen was known about. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.

If the oxygen in an enclosed quantity of air is used up, either by burning a candle in it or by confining an animal, most of the oxygen is converted to carbon dioxide gas which mixes with the nitrogen gas present in the air. Consequently, the discovery of nitrogen is usually accredited to one of Joseph Black's students, the Scottish scientist, Daniel Rutherford, who's also the uncle of the novelist and poet, Sir Walter Scott. Take the relative atomic masses of hydrogen and nitrogen to be 1 and 14 respectively. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. It is taken up by green plants and algae as nitrates, and used to build up the bases needed to construct DNA, RNA and all amino acids.
