what are the characteristics and properties of platinum?
2122
Characteristics: Platinum is a precious metal; soft, silvery-white, and dense with a beautiful lustrous sheen. It is malleable and ductile and has a high melting point. Platinum does not oxidize in air even at high temperatures and is unaffected by common acids.

Properties of P-Block Metals P-block metals have classic metal characteristics: they are shiny, they are good conductors of heat and electricity, and they lose electrons easily. Generally, these metals have high melting points and readily react with nonmetals to form ionic compounds.

Platinum is extracted, processed and purified through a complex series of physical and chemical processes, namely mining, concentrating, smelting and refining. The PGM ore (metal-bearing material in the earth's crust) in the Bushveld is found in horizontal layers usually less than one metre thick.

Platinum (Pt), chemical element, the best known and most widely used of the six platinum metals of Groups 8–10 (VIIIb), 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.

Rhodium, together with ruthenium, palladium, osmium, iridium, and platinum form a group of elements referred to as the platinum group metals (PGM). Rhodium metal is lustrous and silvery white. Rhodium has a higher melting point and lower density than platinum. It has a high reflectance and is hard and durable.

The only ferromagnetic metals (those that are attracted to a magnet) are iron, nickel and cobalt, and some of there alloys. Platinum doesn't stick to a magnet.
