Some heavy periodic elements may be created almost exclusively by such cosmic crashes. Europium, one of the least-common elements in the universe, is a candidate and is used in TVs, lasers ...

Europium was the first isolated, high purity rare earth element to enter the public marketplace, in 1967, as a source of the color red in TV sets. There had been color TV before europium ...

It was not until recent years that the metal was isolated. Europium can be found in the ores bastnasite and monazite. The element has also been identified in the sun and some stars. Europium is ...

When alloyed with other rare earth elements, europium can be used to make permanent magnets, the demand for which has been growing at an exceptional pace owing to their inherent characteristics ...

Their similar charge and atomic structure mean that rare earth elements can often be used interchangeably within a crystal lattice. Unpaired electrons give rare-earth elements unique electrical and ...

Europium metal is now known to be highly reactive; the element's most stable oxidation state is +3, but the +2 state also occurs in solid-state compounds and water.

Europium, which has two common forms ... and most rare earths contain fewer than 14 f-electrons, the elements tend to have multiple orbitals with just one electron. Neodymium atoms, for instance ...

The result is a system that can selectively transport middle rare earth elements, such as europium (Eu 3+) and terbium (Tb 3+), while excluding other ions like potassium, sodium, and calcium.
