Palladium was named after the asteroid Pallas. It is relatively rare and resembles platinum. Palladium is mined and sold as jewelry, bullions and coins, including the Lewis and Clark coin which I used to represent this element. Palladium is also used in dentistry to make crowns as it is very malleable and non-corrosive. It is used medicinally as a treatment for certain types of cancer by inhibiting cell division and causing fewer side effects than some other types of treatments.

The Stillwater igneous complex is located in southern Montana. Long a source for chromium ore, it also produces palladium and other platinum group elements.
