Europium is radioactive, though for most practical purposes it can be treated as stable. 52.2% of europium is stable. 47.8%, is radioactive 151Eu, but the half life of this is long, at 5,000,000,000,000,000,000 years. Like all other elements, europium has radioactive synthetic isotopes.

How can you use europium in a sentence?
Europium is a light pink color. Europium is used as the red phosphor in color television and lasers. Europium is used as a neutron absorber in nuclear research. The atomic weight of Europium is 151.96.
What is the atomic number of europium?
Europium, with the chemical symbol Eu, is the chemical element with the atomic number 63.
What is the state of matter of europium?
Europium is solid at room temperature, as are all metals with the exception of mercury.
What is europium used for?
Because Europium is fairly difficult to obtain it has few practical uses. Europium is unique in the fact that it can absorb more neutrons per atom then any other element. Thus making Europium and its isotopes very valuable in control rods of nuclear reactors. Like many other transition metals Europium is used in producing certain alloys, including striker and lighter flints. It's also been used in the creation of infrared absorbing automotive glass. Europium's compound, Europium Oxide, is often used as a phosphor activator. Europium's other two roles are also involved with phosphors. Europium is used in the production of phosphors for the creation of small lasers. But perhaps what Europium is known best for is the production of the red phosphors that are found in all color television screens.

What are facts about europium?
Europium is not found in nature as a free element. Many minerals contain europium, with the most important sources being bastnäsite and monazite. Depletion or enrichment of europium in minerals relative to other rare earth elements is known as the europium anomaly. Europium has also been identified in the spectra of the sun and certain stars. Europium has no known biological role. Divalent europium in small amounts is the activator of the bright blue fluorescence of some samples of the mineral fluorite (CaF2). The most outstanding examples of this originated aroundWeardale, and adjacent parts of northern England, and indeed it was this fluorite that gave its name to the phenomenon of fluorescence, although it was not until much later that europium was discovered or determined to be the cause.
