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 platinum-group metals (PGMs), also known as the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs), are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 ...
People. Chemical elements are sometimes named after people, especially the synthetic elements discovered (created) after c. 1940. Very few are named after their discoverers, and only two have been named after living people: the element seaborgium was named after Glenn Seaborg, who was alive at the time of naming in 1997; [5] and in 2016 ...
Palladium black. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Palladium black is a coarse, sponge-like form of elemental palladium which offers a large surface area for catalytic activity. It is used in organic synthesis as a catalyst for hydrogenation reactions.
Corinthian bronze (gold, silver) Cunife (nickel, iron) Cupronickel (nickel) CuSil (silver) Cymbal alloys (tin) Devarda's alloy (aluminium, zinc) Hepatizon (gold, silver) Manganin (manganese, nickel) Melchior (nickel); high corrosion resistance, used in marine applications in condenser tubes.
Most gold is mined as native metal and can be found as nuggets, veins or wires of gold in a rock matrix, or fine grains of gold, mixed in with sediments or bound within rock.
Infobox references. Palladium (II) oxide is the inorganic compound of formula Pd O. It is the only well characterised oxide of palladium. [1] It is prepared by treating the metal with oxygen. Above about 900 °C, the oxide reverts to palladium metal and oxygen gas. It is not attacked by acids.
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [1]
