The heaviest naturally occurring element is uranium, which has 92 protons. Its most common form, or isotope, has 146 neutrons. Scientists have also artificially created most of the other elements between uranium and element 118. The newest element was created in a particle accelerator in Dubna, Russia, that shot a beam of calcium-48 ions (containing 20 protons) into a target of californium 249, an artificial element with 98 protons (map of Russia).
