Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish platina, a diminutive of plata "silver". [7] [8] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...
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 ...
The "Final 2023 Critical Materials List" was determined by the United States Department of Energy (DOE), [5] with the Undersecretary for Science and Innovation involvement. . This list incorporates materials deemed critical for energy applications and minerals from the 2022 final list designated by the Department of the Interior through the United States Geological Survey (USG
A technology-critical element (TCE) is a chemical element that is a critical raw material [1] [2] [3] for modern and emerging technologies, [4] [5] [6] resulting in a striking increase in their usage. [4] [7] [1] [8] Similar terms include critical elements, [9] critical materials, [4] energy-critical elements [7] and elements of security. [10]
The table below shows some of the parameters of common superconductors.X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla.
Gelman was the first to find ways of synthesising ethylene (and other alkene) complexes of platinum. Her graduate work in 1941 explained the action of ethylene on platinum (III) salts at low pressure. She found new compounds of platinum (II) and (III) using propylene and butene amongst other alkenes.

In 2006, the company established the not-for-profit American Elements Academics & Periodicals Department. This department provides information on (1) the ways elemental advanced materials are used, [10] (2) global issues affecting the mining and production of the elements [11] [12] and (3) ways to improve the teaching of science at all grade ...
