Platinum Element The Most Precious Metal on Earth


So, today I want to tell you about the most precious metal on Earth – platinum.In the periodic table of chemical elements, platinum is located in the 10th group and is also a part of the so-called platinum group of precious and rare metals.

Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal.Pure platinum is a lustrous, ductile, and malleable, silver-white metal.[12] Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold.

Its physical characteristics and chemical stability make it useful for industrial applications.Its resistance to wear and tarnish is well suited to use in fine jewellery.Platinum is an extremely rare metal, occurring at a concentration of only 0.005 ppm in Earth’s crust.[25][26] It is sometimes mistaken for silver.


Platinum is often found chemically uncombined as native platinum and as alloy with the other platinum-group metals and iron mostly. Platinum is a precious metal commodity; its bullion has the ISO currency code of XPT. Coins, bars, and ingots are traded or collected. Platinum finds use in jewellery, usually as a 90–95% alloy, due to its inertness.
