This article discusses how he and some of his predecessors accommodated the platinum group metals (pgms) in the Periodic Table, and it considers the placing of their three transuranic congeners: hassium (Hs), meitnerium (Mt) and darmstadtium (Ds). Over twenty-five years ago McDonald and Hunt...

Platinum is a transition metal in Group 10 (VIIIB) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Platinum is also a member of a group of metals named after itself. Other platinum metals include ruthenium, rhodium, palladium...
Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile. It has a coefficient of expansion almost equal to that of ...
The platinum group metals occupy the second and third rows of periodic table Group VIII, the first row of which consists of iron (Fe), cobalt (Co), and nickel (Ni). The second-row elements ruthenium (Ru), rhodium (Rh), and palladium (Pd) all have the krypton (Kr, inert gas, atomi...
The term “platinum” is sometimes used to refer to all of a group of six metallic elements that appear together on the periodic table and have similar physical and chemical properties. These platinum-group metals, or PGMs, include: Ruthenium ...
crystallizing the platinum-group metals, the concentration of PGE collected by chromite increased with time. The primary PGMs thus precipitated could have been subsequently modified by low-temperature hydrothermal alteration and metasomatic addition of metals like Cu, Fe, and Ni....
The meaning of PLATINUM METAL is any of the six precious metallic elements including platinum and elements resembling it in chemical and physical properties that belong to group VIII of the periodic table and are often subdivided into two triads one of w
Compounds of metals from the platinum group of the periodic table compounds are encapsulated within a thermoplastic organic polymer using known prior art techniques. The presence of trace amounts of the encapsulated compound on the surface of the microcapsules is avoided by preparing the microcapsules ...
In fact, the six platinum group metals (iridium, palladium, platinum, rhodium, ruthenium and osmium) are all known for their impressive catalytic skills (meaning these metals increase the rate of chemical reaction between substances without changing their physical properties.) In the healthcare field...
