What is EU in periodic table?
europium (Eu), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Europium is the least dense, the softest, and the most volatile member of the lanthanide series.
What is dysprosium used for?
Dysprosium is used in control rods for nuclear reactors because of its relatively high neutron-absorption cross section; its compounds have been used for making laser materials and phosphor activators, and in metal halide lamps.

What is EU in the periodic table?
europium (Eu), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
Why is Eu3+ more stable than Eu2+?
It is generally accepted that in Eu-doped materials responsible for the electronic transition is the Eu2+ cation. This cation is more stable than Eu3+ because a magic configuration 4f7 is formed. Similar situation is possible with Ce-doped material.
Is EU a main group metal?
Europium is also the softest lanthanide, as it can be dented with a fingernail and easily cut with a knife. When oxidation is removed a shiny-white metal is visible. Europium was isolated in 1901 and is named after the continent of Europe….

Why is it called europium?
The name derives from the continent of Europe. It was separated from the mineral samaria in magnesium- samarium nitrate by the French chemist Eugène-Anatole Demarçay in 1896. It was also first isolated by Demarçay in 1901. Europium was discovered by Eugène-Antole Demarçay, a French chemist, in 1896.
