The element lawrentium is named after the American scientist Ernest Lawrence, who developed the first cyclotron particle accelerator. In such an accelerator, parts of atoms are joined together by spinning them in circles. The lawrentium atoms were produced in a cyclotron by colliding boron atoms with californium atoms.
