What element group is platinum?
Group VIII
Platinum is a silvery metallic chemical element, a member of the six transition elements in Group VIII of the periodic table known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium, and platinum).
What is the group or family of platinum?
The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits.
What are the platinum group metals and why do they matter?
The platinum group metals (PGMs) are a family of six structurally and chemically similar elements that are most valued for their wide range of industrial, medical, and electronic applications. These versatile metals play a significant role in many of the products we use every day.
What is platinum group metals?
The platinum group metals (PGMs) comprise 6 elements, which are platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have high melting points, high heat resistance, high corrosion resistances, and unique catalytic properties.
What type of metal is platinum?
Platinum is a silver-white metal — it was once known as “white gold.” It is extremely resistant to tarnishing and corrosion (which makes it known as a “noble metal”) and is very soft and malleable, making it easy to shape; ductile, making it easy to stretch into wire; and unreactive, which means it doesn’t oxidize and …
What are platinum group minerals?
The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have similar physical and chemical properties and occur together in nature.
What are platinum group elements used for?
Although platinum is well known for its use as jewelry and as an investment commodity, the major applications of PGE are industrial. Their leading use is in catalytic converters, which decrease hydrocarbon, carbon monoxide, and nitrous oxide emissions in automobile exhaust.
What are the function of platinum?
Platinum is used in the chemicals industry as a catalyst for the production of nitric acid, silicone and benzene. It is also used as a catalyst to improve the efficiency of fuel cells. The electronics industry uses platinum for computer hard disks and thermocouples.
