Copernicium is an element that doesn't exist in nature. It is
created in the lab when a zinc atom and a lead one collide at 30000
km/s. This element has no stable isotopes. All of them emit radioactive
particles and transform in a different element after a very little time
The name, copernicium, in homenage to the Polish astronomer Nicolas
Copernico
