Gold chalcogenides are gold compounds with anions from periodic table group 16, known as the chalcogens. Gold chalcogenides often appear as minerals. Gold chalcogenides have stability that is reversed from typical chalcogenides. For gold, the tellurides are the most stable, while the sulfide and oxide are metastable. For most other metals, it is the other way around.

A periodic table group is a vertical column in the periodic table of the chemical elements. ... The chalcogens are the name for the periodic table group 16 (old-style: VIB or VIA) in the periodic table. ... Minerals are natural compounds formed through geological processes. ... A metastable system with a weakly stable state (1), an unstable transition state (2) and a strongly stable state (3) Metastability is the ability of a non-equilibrium state to persist for some period of time. ...

Gold tellurides

AuTe₂ is present as a number of minerals, the most common being calaverite. Calaverite is the most important source of gold after native gold. Minerals are natural compounds formed through geological processes. ... Calaverite or Gold telluride is an uncommon telluride of gold; it is a metallic mineral. ... Calaverite or Gold telluride is an uncommon telluride of gold; it is a metallic mineral. ...

Gold selenides

AuSe exists in two forms, AuSe and Au₂Se₃.

Gold sulfides

Au₂S is metastable, but mixed silver-gold sulfides like AgAuS do exist. General Name, Symbol, Number silver, Ag, 47 Chemical series transition metals Group, Period, Block 11, 5, d Appearance lustrous white metal Atomic mass 107. ...
