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). Roentgenium (Rg) belongs to this group of elements based on its electronic configuration, but it is a short-lived transactinide with a 22.8 seconds half-life that has only been observed in laboratory conditions. The name "coinage metals" is often used in casual speech to refer to these elements, but various cultures have used many other metals in coinage including aluminium, lead, nickel, stainless steel, and zinc.
