Wikipedia
Palladium
Palladium is a chemical element with the symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by the English chemist William Hyde Wollaston. He named it after the asteroid Pallas, which was itself named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). They have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. More than half the supply of palladium and its congener platinum is used in catalytic converters, which convert as much as 90% of the harmful gases in automobile exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into nontoxic substances (nitrogen, carbon dioxide and water vapor). Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, in which hydrogen and oxygen react to produce electricity, heat, and water. Ore deposits of palladium and other PGMs are rare. The most extensive deposits have been found in the norite belt of the Bushveld Igneous Complex covering the Transvaal Basin in South Africa, the Stillwater Complex in Montana, United States; the Sudbury Basin and Thunder Bay District of Ontario, Canada, and the Norilsk Complex in Russia. Recycling is also a source, mostly from scrapped catalytic converters. The numerous applications and limited supply sources result in considerable investment interest.

palladium
Palladium is a rare, lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. It is one of the six platinum-group metals and it's used in many industrial processes. Notably, palladium is used in catalytic converters to transform harmful gases from auto exhausts into less harmful substances. It is also used in electronics, medicine, hydrogen purification, and jewelry. On the periodic table of elements, palladium is identified by the symbol Pd and atomic number 46.
Webster Dictionary
Palladiumnoun
any statue of the goddess Pallas; esp., the famous statue on the preservation of which depended the safety of ancient Troy
Palladiumnoun
hence: That which affords effectual protection or security; a sateguard; as, the trial by jury is the palladium of our civil rights
Palladiumnoun
a rare metallic element of the light platinum group, found native, and also alloyed with platinum and gold. It is a silver-white metal resembling platinum, and like it permanent and untarnished in the air, but is more easily fusible. It is unique in its power of occluding hydrogen, which it does to the extent of nearly a thousand volumes, forming the alloy Pd2H. It is used for graduated circles and verniers, for plating certain silver goods, and somewhat in dentistry. It was so named in 1804 by Wollaston from the asteroid Pallas, which was discovered in 1802. Symbol Pd. Atomic weight, 106.2

Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. Over half of the supply of palladium and its congener platinum goes into catalytic converters, which convert up to 90% of harmful gases from auto exhaust into less-harmful substances. Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment and jewelry. Palladium plays a key role in the technology used for fuel cells, which combine hydrogen and oxygen to produce electricity, heat, and water. Ore deposits of palladium and other PGMs are rare, and the most extensive deposits have been found in the norite belt of the Bushveld Igneous Complex covering the Transvaal Basin in South Africa, the Stillwater Complex in Montana, United States, the Thunder Bay District of Ontario, Canada, and the Norilsk Complex in Russia.

Chambers 20th Century Dictionary
Palladium
pal-lā′di-um, n. a statue of Pallas, on the preservation of which the safety of ancient Troy depended: any safeguard: a rare metal in colour and ductility resembling platinum.—adj. Pallā′dian.—v.t. Pallā′diumise, to coat with palladium. [L.,—Gr. palladion—Pallas, Pallados, Pallas.]
The Nuttall Encyclopedia
Palladium
a statue of Pallas in Troy, on the preservation of which depended the safety of the city, and from the date of the abstraction of which by Ulysses and Diomedes the fate of it was doomed; it was fabled to have fallen from heaven upon the plain of Troy, and to have after its abstraction been transferred to Athens and Argos; it is now applied to any safeguard of the liberty of a State.
U.S. National Library of Medicine
Palladium
A chemical element having an atomic weight of 106.4, atomic number of 46, and the symbol Pd. It is a white, ductile metal resembling platinum, and following it in abundance and importance of applications. It is used in dentistry in the form of gold, silver, and copper alloys.
The Standard Electrical Dictionary
Palladium
A metal of the platinum series. It has the highest power of occlusion, q.v., of all metals. It is the characteristic ingredient of non-magnetic watch alloys. Palladium used as an electrode in the electrolysis of water will occlude 936 volumes of hydrogen, and the hydrogen-palladium alloy will exceed in size the original electrode.
Mythology
Palladium
(Palla′dium). A famous statue of the goddess Pallas (Minerva). She is sitting with a spear in her right hand, and in her left a distaff and spindle. Various accounts are given of the origin of the statue. Some writers say that it fell from the skies. It was supposed that the preservation of the statue would be the preservation of Troy; and during the Trojan War the Greeks were greatly encouraged when they became the possessors of it.
