Nuclear missing link created at last: Superheavy element 117
Element 117 fills in the final gap in the list of observed elements up to element 118
Like all superheavy atoms, element 117 is unstable, lasting only fractions of a second before self-destructing in a cascade of lighter elements and particles. After smashing calcium atoms into a target of berkelium in a particle accelerator at the Joint Institute for Nuclear Research in Dubna, Russia, the team deduced the fleeting existence of element 117 by studying the daughter particles emitted as the atom decayed.
Despite the atom's short lifetime, element 117 lives longer than many lighter elements. The discovery confirms theories that predict that 117 and its recently-synthesized cousins, elements 116 and 118, exist in an island of stability on the periodic table. Only synthesizing increasingly heavy elements will show just how far the stable region extends up the list of elements.
While there is no known practical application for such short-lived atoms, the synthesis of superheavy elements is vital for testing models that explain how the neutrons and protons that make up all the elements bind together. Such models in turn help explain the relative proportion of more common elements in the universe, as well as offering predictions of other exotic atoms that may be stable enough occur naturally on Earth or in meteorites.
