List of Noble Metals

Here is a list of noble metals, which are metals that resist oxidation and corrosion. RutheniumRhodiumPalladiumSilverOsmiumIridiumPlatinumGold Some lists include mercury as a noble metal. Rhenium is also included as a noble metal by some scientists and engineers. While noble metals retain their shiny color, base metals tend to oxidize in moist air. However, some metals that resist corrosion are not considered noble metals. These include titanium, niobium, and tantalum. In atomic physics, the noble metal group consists of copper, silver, and gold. Only these three elements have completely filled d-subshells. Most noble metals are valuable and rare, yet the noble metals are not exactly the same as the precious metals. See a chart of noble and precious metals. Source Brooks, Robert R., ed. (1992).
