Who Am I ?
I am number 63 on the Periodic Table and my weight? Well, if you have to ask, my atomic weight - or amu - is 151.964.
My friends call me Eu for short, but you can call me Europium, the rarest and most reactive of the Earth Metals. My friendship doesn't come cheap though! To buy just 100 grams of me, you have to spend $3600! I'm worth it though, I promise.
