Europium is a chemical element discovered in the very beginning of the 20th century and named after the continent of Europe. It is a lanthanide. It occurs naturally on our planet in some minerals and is extracted from them. In its pure form, Europium is a soft light grey color metal which is quite reactive and non toxic. It doesn’t have a lot of applications and can be used in nuclear energy producing facilities, in producing low energy bulbs and some super strong alloys. Europium can be found on Euro notes, on the security marks.
