The MacArthur-Forrest process produces this element's cyanide complex. It can have a -1 oxidation state, as it is the most electronegative metal. A sample of this element was surrounded by a ring of zinc sulfide by Marsden and Geiger. Although it is usually quite unreactive in elemental form, it dissolves in a solution of nitric acid and hydrochloric acid called aqua regia. This element was bombarded with alpha particles an experiment that discovered the atomic nucleus, performed by Rutherford using a thin foil made of this element. For 10 points, name this yellow metal with symbol Au.
