The chemistry of precious metals—primarily the (platinum, palladium, rhodium, ruthenium, iridium, and osmium) along with gold and silver —is defined by their remarkable resistance to corrosion, high density, and unique electronic configurations. Chemistry of Precious Metals

They possess high positive reduction potentials (e.g., ) are central to modern solar energy conversion

Precious metals are often called "noble" because they resist oxidation and protonic acids. Relativistic color Electronics
