Characteristics of precious metals

  • Precious metals withstand corrosion
  • The chemical bonds in precious metals are thermally unstable. This means that they do not rust or oxidize, but their bonded structure changes drastically upon heating.
  • Precious metals are in general not affected by hydrochloric acid.
  • There are also chemical properties that other metals have, similar to copper, gold, and silver.
