Etymology
Description
It is a metal element with a silvery-white luster. Dysprosium is among the lanthanides. It is relatively stable in air at room temperatures. However, it dissolves in mineral acids by converting hydrogen. It is found in rare earth minerals. It has seven natural isotopes and eight radioisotopes. Among these, Dy-154 is the most stable with a half-life of 3*10^6 years. Dysprosium is used in CD production and as a neutron absorber in nuclear fission reactors. It was discovered in France in 1886 by Paul Emile Lecoq de Boisbaudran. Its name comes from the Greek word dysprositos, meaning "hard to get."
