Platinum is a metallic element with symbol Pt and atomic number 78. It is a luxurious and precious metal that resists tarnish and corrosion, and has a high melting point and remarkable catalytic properties. Discovery and Naming. Platinum was known to indigenous people in Central and South America long before European discovery.

With the periodic table symbol Pt, atomic number 78, atomic mass of X g.mol-1, and electron configuration [Xe] 4f145d96s1, platinum is a soft, dense, ductile, and malleable silvery-white metal.

Last updated: May 17, 2022. A column of platinum the size of a man is about 25 times heavier (it weighs an amazing 2000kg or 4,400lb)! Platinum is a dense, expensive, and relatively rare, silvery-white metal—and those may be the only things you know about it.
