This element's anomalous electron configuration features a full 3d orbital and a half-filled 4s orbital.
It's not palladium, but a catalyst of this transition metal is used in Sonogashira coupling. The most common method of extracting this element from ore involves separating it from iron and sulfur in chalcopyrite. Muntz metal, an alloy of zinc, iron, and this metal, is used in shipbuilding to prevent biofouling. This element's anomalous electron configuration features a full 3d orbital and a half-filled 4s orbital. For 10 points, name this transition metal whose most common industrial use is in electrical wire.
