 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 .
