Dysprosium (Dy) is a chemical element of the periodic table, located in the period 6, and has the atomic number 66. It is the tenth element in the lanthanide series. It is a soft, lustrous, silvery-white metal, whose name comes from the Greek word “dysprositos”, which means hard to get. It is never found freely in nature and is counted as one of the rare earth elements.
