  2. Noble metal - Wikipedia

    en.wikipedia.org/wiki/Noble_metal

    The expression noble metal is sometimes confined to copper, silver, and gold since their full d-subshells can contribute to their noble character. [12] There are also known to be significant contributions from how readily there is overlap of the d-electron states with the orbitals of other elements, particularly for gold. [ 13 ]

  3. Galvanic series - Wikipedia

    en.wikipedia.org/wiki/Galvanic_series

    The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in ...

  6. Molten-Salt Reactor Experiment - Wikipedia

    en.wikipedia.org/wiki/Molten-Salt_Reactor_Experiment

    The deposition of some elements ("noble metals") was expected, but the MSRE provided quantitative data on relative deposition on graphite, metal, and liquid-gas interfaces. Heat transfer coefficients measured in the MSRE agreed with conventional design calculations and did not change over the life of the reactor. Limiting oxygen in the salt ...

  7. Native state (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Native_state_(metallurgy)

    Many metals are found in uncombined metallic form, in varying degrees of purity. These "metals found as metals" are referred to as native metals, which are a subset of native element minerals. The most well-known native metals are native copper and gold. Nonreactive noble metals usually occur in nature as native metals.

    This list of chemical elements named after places includes elements named both directly and indirectly for places. 41 of the 118 chemical elements have names associated with, or specifically named for, places around the world or among astronomical objects.

  9. Precious metal - Wikipedia

    en.wikipedia.org/wiki/Precious_metal

    Precious metals, particularly the noble metals, are more corrosion resistant and less chemically reactive than most elements. They are usually ductile and have a high lustre . Historically, precious metals were important as currency but they are now regarded mainly as investment and industrial raw materials .
