Although it's not Chromium, this element's electronic structure is an exception to the Aufbau principle, as it has only 1 electron in the 4s subshell. This element lies above silver on the periodic table, and it is second to that element in having the highest (*) thermal and electrical conductivity. After exposure to air or seawater over a long period of time, this element develops a patina called verdigris, which lends a green color to the Statue of Liberty. Often used in piping and electrical wires, for 10 points, identify this red-orange transition metal element with symbol Cu.
