Palladium is a chemical element with symbol Pd and atomic number 46.

It is a rare and lustrous silvery-white metal discovered in 1803 by 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).

These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.

Platinum is a chemical element with symbol Pt and atomic number 78.

It is a dense, malleable, ductile, highly unreactive, precious, gray-white transition metal.

Its name is derived from the Spanish term platina, translated into "little silver".

A precious metal is a rare, naturally occurring metallic chemical element of high economic value.

Chemically, the precious metals tend to be less reactive than most elements (see noble metal).

They are usually ductile and have a high lustre.

Historically, precious metals were important as currency but are now regarded mainly as investment and industrial commodities.

Gold, silver, platinum, and palladium each have an ISO 4217 currency code.

Gold is a chemical element with symbol Au (from) and atomic number 79.

In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.

Chemically, gold is a transition metal and a group 11 element.

It is one of the least reactive chemical elements and is solid under standard conditions.

Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits.

It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium.

Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.

There are 18 numbered groups in the periodic table, but the f-block columns (between groups 2 and 3) are not numbered.

The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same core charge), as most chemical properties are dominated by the orbital location of the outermost electron.
