Europium Nitride

Europium is the most reactive of the rare earth elements; it rapidly oxidizes in air, and resembles calcium in its reaction with water; deliveries of the metal element in solid form, even when coated with a protective layer of mineral oil, are rarely shiny. Europium ignites in air at about 150 °C to 180 °C. It is about as hard as lead and quite ductile.
