A silvery-white metallic element and member of the lanthanide series, atomic number 63, used in red phosphors for television and computer screens.
From Latin 'Europa' (the continent Europe); named in 1901 by chemist Eugène-Anatole Demarçay to honor Europe and continue the tradition of naming lanthanides after places.
Europium glows red in your old TV screen, making it one of the few elements you've literally seen glow—it's so good at producing red light that it's irreplaceable in displays, meaning your entertainment history is written in this rare earth element.
