Rareearth element Wikipedia

As seen in the chart to the right, rareearth elements are found on earth at similar concentrations to many common transition metals. The most abundant rareearth element is cerium, which is actually the 25th most abundant element in Earth's crust, having 68 parts per million (about as common as copper).The exception is the highly unstable and radioactive promethium "rare earth" is quite scarce.
