Examples

  • Even though the name ununseptium (symbol: Uus) is only temporary, Russian and U.S. scientists still have made an important discovery of a new chemical element, one with an atomic number of Z = 117.

    OCAU News

  • The element - which has no formal name but is known as ununseptium - was created by accelerating an atom of calcium (element 20) in a cyclotron and smashing it into an atom of berkelium (element 97).

  • The element 117 is roughly 40 per cent heavier than lead and has been given the temporary name ununseptium, which refers to its atomic number.

  • The systematic element name placeholder for element Z=117, also known by the temporary symbol Uus, as oroboros listed in the comment below. Also historically called eka-astatine in Dmitri Mendeleev's naming system for predicted but as-yet undiscovered elements.
