What is a main use of platinum group metals?
These versatile metals play a significant role in many of the products we use every day. Platinum (Pt): Platinum is probably the most recognized of the PGMs because of its use in jewelry, but its main application is the manufacture of catalytic converters as well as other industrial applications.
Why are Platinums called group metals?
Platinum is probably the best known of this group of metals, due in large part to its use in jewelry making. It is dense, stable, and rare, and widely used in medical and electronic devices and applications. Palladium is a soft, silvery-white metal valued for its catalytic properties.
Is platinum Reactive or nonreactive?
Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth’s crust. They have high melting points, are dense or heavy and are non-reactive with other elements.
Is platinum a mineral?
The platinum group metals (PGMs) are among the rarest mineral commodities in Earth’s crust. They include iridium, osmium, palladium, platinum, rhodium and ruthenium. The PGMs occur together in nature, closely associated with nickel and copper, primarily in two major types of ore deposits.
Is platinum a compound or element?
platinum (Pt), chemical element, the best known and most widely used of the six platinum metals of Groups 8–10, Periods 5 and 6, of the periodic table. A very heavy, precious, silver-white metal, platinum is soft and ductile and has a high melting point and good resistance to corrosion and chemical attack.
Is platinum a noble metal?
The short list of chemically noble metals (those elements upon which almost all chemists agree) comprises ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), platinum (Pt), gold (Au) and silver (Ag).
