Definition of the Platinum Element
A silver-white metallic element occurring worldwide, usually mixed with other metals such as iridium, osmium, or nickel. It is ductile and malleable, does not oxidize in air, and is used as a catalyst and in electrical components, jewelry, dentistry, and electroplating.

Origin / Meaning of the name Platinum
The name originates from the Spanish word platina meaning 'little silver'

Classification of the Platinum Element
Platinum 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.

Facts about the History and Discovery of the Platinum Element
Platinum was discovered by astronomers Antonio de Ulloa and Don Jorge Juan y Santacilia in 1735.  However the first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger (1484-1558). Charles Wood independently isolated the element in 1741. The alchemical symbol for platinum was made by joining the symbols of silver and gold

Platinum - 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 Platinum is just one element that can be found.
