Platinum is a
chemical element with the chemical
symbol Pt and an atomic number of 78.
Its name is derived from the Spanish
term platina del Pinto, which is
literally translated into "little silver
of the Pinto River."[1] It is a dense,
malleable, ductile, precious, gray-white
transition metal. Even though it has six
naturally occurring isotopes, platinum
is one of the rarest elements in the
Earth's crust and has an average
abundance of approximately 0.005 mg/kg.
It occurs in some nickel and copper ores
along with some native deposits, mostly
in South Africa, which accounts for 80%
of the world production.
As a member of
the platinum group of elements, as well
as of the group 10 of the periodic table
of elements, platinum is generally
unreactive. It exhibits a remarkable
resistance to corrosion, even at high
temperatures, and as such is considered
a noble metal. As a result, platinum is
often found chemically uncombined as
native platinum. Because it occurs
naturally in the alluvial sands of
various rivers, it was first used by
pre-Columbian South American natives to
produce artifacts. It was referenced in
European writings as early as 16th
century, but it was not until Antonio de
Ulloa published a report on a new metal
of Colombian origin in 1748 that it
became investigated by scientists.
