Copernicium atoms are radioactive, and survive for only a few minutes before decaying. Copernicium is created in particle accelerators by colliding lead atoms with zinc atoms. Only a few atoms of this artificial element have been produced. Copernicium is named after Nicolaus Copernicus, the astronomer who proposed the theory that our planet orbits the Sun.
