elements and compounds that extract gold


Displacement Reactions and the Reactivity Series S

The more reactive a metal the more difficult it is to extract from its compounds. Copper, silver and gold appear as elements in the earth due to their unreactivity with their environment. They are easy to extract.

Gold Table of Elements and Chemistry

If gold chloride is heated gently, it will decompose to release the pure elements again. Unusually for a metal, gold can also form compounds (aurides) in which its oxidation number is negative ( 1). For example, gold can combine with cesium to form cesium auride, CsAu, and rubidium to form rubidium auride, RbAu.

The Elemental Compositions of Metal Alloys Interest

Alloys are a mixture of elements, where at least one of the elements is a metal. There are over 80 metals in the periodic table of elements, and we can mix selections of these different metals in varying proportions, sometimes with non metals too, to create alloys.
