Definition of the Palladium Element
A soft, ductile, steel-white, tarnish-resistant, metallic
element occurring naturally with platinum, especially in gold,
nickel, and copper ores. Because it can absorb large amounts of
hydrogen, it is used as a purification filter for hydrogen and a
catalyst in hydrogenation. It is alloyed for use in electric
contacts, jewelry, nonmagnetic watch parts, and surgical
instruments. The element played an essential role in the
Fleischmann-Pons experiment, also known as cold fusion.
Origin / Meaning of the name Palladium
Named after the asteroid
Pallas which was discovered two years before in 1801
Classification of the Palladium Element
Palladium is
classified as a "Transition Metal" which are located in Groups 3 -
12 of the Periodic Table. An Element classified as a Transition
Metals is ductile, malleable, and able to conduct electricity and
heat.

Palladium and the
Periodic Table
Check out Palladium 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 Palladium 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.
Palladium - 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 but still all fitting into his concept of
the "Periodic Table" in which
Palladium is just one element
that can be found.
