Palladium, Pd, is one of the six platinum-group elements (Ru, Rh, Pd, Os, Ir, Pt). With an atomic number of 46, it lies in the second transition series of the Periodic Table in the group VIIIA. An...Capobiano, Christopher J....
In recent years there have been several reports on concomitant patch test reactions to palladium and nickel, which belong to the same group in the periodic table. Exposure to palladium mainly takes place via dental alloys and jewelry. However, the clinical relevance of simultaneous reactivity to ...
Palladium (Pd), chemical element, the least dense and lowest-melting of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, used especially as a catalyst (a substance that speeds up chemical reactions withoutSee...
shaped, grayish-white metallic element that occurs naturally with platinum. Because it can absorb large amounts of hydrogen, it is used as a catalyst in reactions involving hydrogen. Palladium and its alloys are used to make electrical contacts and jewelry.Atomic number46. SeePeriodic Table. ...
Chemical PropertiesPalladium, a transition element belonging to group III in the periodic table (nickel group) and light platinum metals, is a medium-hard, moderately forgeable, and ductile silverwhite metal. Soluble in aqua regia, hot nitric acid, sulfuric acid, slightly soluble in hydrochloric ...
