europium

Europium is not found in nature as a free element.

Europium is responsible for the red in color television sets.

Europium is also used in the manufacture of fluorescent glass.

Relative to most other elements, commercial applications for europium are few and rather specialized.

Europium has the configuration Xe4f7 and is a strong reducing agent.

Europium is a chemical element with the symbol Eu and atomic number 63.

Only 0.2% of the rare earth element content is europium.

Color TV screens contain between 0.5 and 1 g of europium.

It may be formed by ignition of europium metal.

There are no clear indications that europium is particularly toxic compared to other heavy metals.

Europium is a ductile metal with a hardness similar to that of lead.

Europium has no significant biological role and is relatively non-toxic compared to other heavy metals.

However, the europium content was at least double that of a typical monazite.

The fractional crystallization of the oxides then yielded europium in 1901.

Europium is the most reactive rare earth element.

Some properties of europium are strongly influenced by its half-filled electron shell.

It has been shown that europium is "responsible" for about 12 grams of promethium in the Earth's crust.

The basalts show a large negative europium anomaly.

This isotope is produced in a nuclear reactor from europium or enriched gadolinium.

The oxide compound europium titanate is pretty boring on its own.

In particular, it is an A2-type star showing an excess of the elements chromium and europium.

Europium, neodymium, and other rare earth elements are used to dope glasses for lasers.

Europium concentrations tend to be low, about 0.05%.

Divalent europium is the source of the blue fluorescence, when seen in the mineral fluorite.

However, a package duly arrived in the mail, containing several pounds of genuine europium oxide.
