What is Nitrogen? Facts about the
Discovery and
History of the Nitrogen
Element
Nitrogen was discovered by
the English chemist Rutherford in 1772 who determined that the
air in which animals had breathed, even after removal of the
exhaled carbon dioxide, was no longer able to burn a candle. A little later Scheele
showed it to be a constituent of air, and Lavoisier gave it the
name azote, signifying that it would not support life. The name
nitrogen was afterwards given it because of its presence in
saltpeter or niter. The term azote and symbol Az are still
retained by the French chemists.
Carl Wilhelm
Scheele
Carl Scheele (9 December
1742 – 21 May 1786) was a German chemist who made a number of
important chemical discoveries before many others but was rarely
given the credit for his findings. For instance, although
Scheele discovered oxygen Joseph Priestley published his
findings first so was given the credit. Carl Scheele also
identified molybdenum,
Tungsten,
Barium,
Hydrogen
and
Chlorine
before Humphry Davy and other scientists.

Antoine Lavoisier
Antoine Lavoisier was famous for his care in quantitative
experiments, for demonstrating the true nature of combustion,
for introducing system into the naming and grouping of chemical
substances. Lavoisier was executed in 1794 during the French
Revolution.

Nitrogen as on the
Periodic Table
Check out Nitrogen on the Periodic Table which arranges each chemical
element according to its atomic number, as based on the
Periodic Law, so that chemical elements with similar properties are in the
same column. Our Periodic Table is simple to use - just click on
the symbol for Nitrogen as on the Periodic Table for additional information and for an instant
comparison of the Atomic Weight, Melting Point, Boiling Point and
Mass - G/cc with any other element. An invaluable source of facts
and information as a Chemistry reference guide.

What is Nitrogen - IUPAC and the
Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985 and
now recognises more periods and elements than
Dimitri
Mendeleev knew in his day in his day but still all fitting into his concept of
the "Periodic Table" in which
Nitrogen is just one element
that can be found.
