Here is a brief description of europium.
Europium is about as hard as lead and is quite ductile.
It is the most reactive of the rare earth metals, quickly oxidising in air. It resembles calcium in its reaction with water. It is used in television screens to produce a red colour. Here is a brief summary of the isolation of europium. Europium metal is available commercially so it is not normally necessary to make it in the laboratory, which is just as well as it is difficult to separate it from as the pure metal.
