What family group is platinum in?
The platinum family, or platinum group, is comprised of six metallic elements; platinum, palladium, iridium, osmium, rhodium, and ruthenium. Along with gold and silver, they are considered the noble or precious metals.
What mineral group is platinum in?
They have high melting points, are dense or heavy and are non-reactive with other elements. The platinum group metals (PGM) include ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir) and platinum. Of these elements, only platinum and palladium are found in a pure form in nature.
Is platinum a main group element?
In chemical terms the six main platinum group elements (PGE), ruthenium, rhodium, palladium, osmium, iridium and platinum, belong to the group VIII transition metals, to which also belong iron, nickel and cobalt. These elements have long been considered, when grouped with gold and silver, as ‘precious metals’.

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 a mineral 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.
What is so special about platinum?
Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold. The metal has excellent resistance to corrosion, is stable at high temperatures and has stable electrical properties.
How rare is platinum compared to gold?
Platinum is 30 times more rare than gold. If all the platinum ever mined were melted and poured into an Olympic-sized pool, the platinum would barely reach your ankles. Gold, however, would fill three pools. Precious platinum is truly as rare as your love.
What are the characteristics of platinum family?
They are highly resistant to wear and tarnish, making platinum, in particular, well suited for fine jewellery. Other distinctive properties include resistance to chemical attack, excellent high-temperature characteristics, high mechanical strength, good ductility, and stable electrical properties.

What element family does platinum belong to?
Platinum belongs to the transition metals family, which includes the 38 elements found in groups 3 through 12 on the periodic table. The metals in the family are ductile and malleable while conducting electricity and heat.
Who discovered the element platinum?
Platinum is a chemical element. Its atomic number is 78 and it is represented by the chemical symbol Pt. It is greyish white metallic element commonly mixed with other metals for instance, osmium, nickel or iridium . It was discovered in Peru in 1735 by Antonio de Ulloa, a Spanish explorer and Jorge Juan y Santacilia, a Spanish scientist.
What is platinum family?
Platinum is the most abundant of a family of six heavy metals, all very similar to one another, and they are always found together. The platinum family consists of two triads analogous to the triad of iron, cobalt and nickel directly above them in the Periodic Table .
