Platinum is a chemical element on the periodic table.
Platinum is named after the Spanish phrase “platino” which translates to “little silver”.
Platinum is a dense precious metal with a silvery white color that is both ductile and malleable.
Platinum was discovered in trace amounts of gold by archeologists in ancient Egyptian burials dating as far back as 1200 BC. However, French scientist and explorer Antonio de Ulloa is credited with the discovery of platinum in 1735. Ulloa took samples from Colombia and Peru and established a mineralogy lab in 1748 to study platinum.
