28 Απρ 2021 · The platinum group metals or PGMs are a cluster of six transition metals on the periodic table. They are noble and precious metals with chemical and physical properties similar to that of platinum and occurring in the same ore deposits.
17 Μαΐ 2022 · Physical and chemical properties. Physically, platinum is heavy, soft, malleable (easy to work—only silver and gold are easier to shape), and ductile (easy to draw into wires) and has a fairly high melting point (~1770°C or 3220°F). Chemically, it's often described as a noble metal because it is so unreactive.
