Properties of Europium (Eu)
Europium is a chemical element with the symbol (Eu) and atomic number 63. It is a rare earth element and a member of the lanthanide series in the periodic table. Europium is named after the continent of Europe, and it was first isolated in 1901. It is primarily used in the production of phosphors, which are materials that emit light when exposed to certain types of radiation.
The following table provides a comprehensive list of europium (Eu) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
