I 1901 isolerte Demarçay europium for første gang. Europium var det syvende og siste grunnstoffet som ble funnet i mineralet ceritt.</p>

Leveranser av europium har derfor sjelden metallisk glans når det kommer fram, selv ikke med et beskyttende oljelag. Europium antenner i luft ved 150-180 °C (<a href="/wno/Tenntemperatur" title="Tenntemperatur" wx:linktype="known" wx:pagename="Tenntemperatur" wx:page_id="424185" id="wx265">tenntemperatur</a>).
