Platinum, Pt

Platinum (Pt) is a dense, malleable, and highly unreactive metal with a characteristic silvery-white appearance. It is one of the least reactive metals, showing significant resistance to corrosion, even at high temperatures. This makes it particularly valuable in industrial applications. Optically, platinum mirrors can be used in specialized optical instruments due to their durability and resistance to oxidation. Additionally, because of its inertness and ability to withstand high temperatures, platinum is commonly used as a substrate or material for thin-film deposition in various optical and electronic applications. In the broader industry, it's heavily used in catalytic converters for automobiles, in laboratory equipment, and in making jewelry due to its attractive appearance and resistance to tarnish.
