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.
Gold is a chemical element with the symbol Au (from the Latin word aurum) and the atomic number 79. In its pure form, it is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals.
