The
Discovery of Barium
Barium was discovered by in
1774 by Carl Scheele and extracted by Sir Humphry Davy
in 1808.
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.

Sir Humphry
Davy
Sir Humphry Davy (1778-1829) isolated
Sodium,
Lithium,
Potassium, barium, strontium, and calcium by means of
electrolysis; demonstrated the elementary nature of chlorine;
invented the safety lamp; discovered the stupefying effects of
nitrous oxide.
Sir Humphry Davy (1778 - 1829)
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.

Barium as on the
Periodic Table
Check out Barium 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 Barium 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 Barium - 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
Barium is just one element
that can be found.
