Platinum's name is derived from the Spanish term platina del Pinto, which is literally translated into "little silver of the Pinto River".It is adense, malleable, ductile, precious, gray-white transition metal.
Platinum is used in catalytic converters, laboratory equipment, electricalcontacts and electrodes, platinum resistance thermometers, dentistryequipment, and jewelry. Because only a few hundred tonnes are produced annually, it is a scarce material, and is highly valuable and is a majorprecious metal commodity. Being a heavy metal, it leads to health issues upon exposure to its salts, but due to its corrosion resistance, it is not as toxic as some metals. Its compounds, most notably cisplatin, are applied inchemotherapy against certain types of cancer.
