- Europium is not found freely in nature. Most of the minerals comprise of europium with the vital sources being monazite and bastnasite.
- It is a soft white-silvery metal. The enrichment or depletion of europium in minerals related to other rare earth elements is termed as europium anomaly.
- It is used as control rods in nuclear reactors due to its effectiveness in absorbing neutrons.
- Europium oxide has its application as phosphor activator.
- Europium-doped plastics are used as laser materials and for making thin superconducting alloys.
- It is used in the euro currency as an anti-forgery measure.
- Europium is a member of the lanthanides group of elements. It is the most active element among the lanthanides.
- It reacts very quickly with water and gives off hydrogen. It reacts strongly with oxygen in the air and spontaneously catches fire.
- There are two stable isotopes of Europium that exist in nature, europium-151 and europium-153.
