Precious metals Precious metals

What makes a precious metal precious are its chemical properties. All of these metals are not affected, or are scarcely affected, by oxidation. As a result, precious metals retain the same fixed mass as well as their quality and value. They are ideal for jewels and coins

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.
