Platinum

Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silver-white transition metal. Its name is derived from the Spanish term platino, meaning "little silver". Platinum is one of the least reactive metals, and is inert to air and water. It is the most resistant metal to corrosion, even at high temperatures. Platinum is used in jewelry, dentistry, and other applications where resistance to corrosion is important.

Platinum is also used in the production of catalytic converters for automobiles. Catalytic converters are devices that convert harmful exhaust gases into less harmful substances. Platinum is a key component of catalytic converters because it is able to catalyze the reaction of harmful exhaust gases into less harmful substances.

Platinum is a valuable metal and is often used as a store of value. Platinum is also used as an investment, and its price can fluctuate significantly.
