A Group 11 element is one in the series of elements in group 11 (IUPAC style) in the periodic table, consisting of transition metals which are the traditional coinage metals of copper (Cu), silver (Ag), and gold (Au).
Unter einer Gruppe des Periodensystems versteht man in der Chemie jede Spalte des Periodensystems. Alle Elemente einer Gruppe besitzen die gleiche Anzahl an Valenzelektronen und haben daher ähnliche chemische Eigenschaften.
