Europium is a ductile metal with a hardness similar to that of lead. It crystallizes in a body-centered cubic lattice. Some properties of europium are strongly influenced by its half-filled electron shell.Europium has the second lowest melting point and the lowest density of all lanthanides.uropium is a ductile metal with a hardness similar to that of lead.

Truly pure europium was not isolated until the 1960s, when advanced techniques were used to extract the reactive element from monazite. Ad. In addition to being used in televisions, europium is also occasionally used as a dopant in lasers. Scientists and researchers also work with europium on a variety of projects, and geologists use the europium content of rocks to learn more about them. The element is utilized in some genetic screening tests, as well.
