Ununseptium - Naming

Naming

Using Mendeleev's nomenclature for unnamed and undiscovered elements, ununseptium should be known as eka-astatine or dvi-iodine. In 1979 IUPAC published recommendations according to which the element was to be called ununseptium (with the corresponding symbol of Uus), a systematic element name as a placeholder, until the discovery of the element is confirmed and a name is decided on. The recommendations are largely ignored among scientists, who call it "element 117", with the symbol of (117) or even simply 117. According to current guidelines from IUPAC, the ultimate name for all new elements should end in "-ium", which means the name for ununseptium will end in "-ium", not "-ine", even if ununseptium turns out to be a halogen, which traditionally have names ending in "-ine".

No official name has yet been suggested for the element. However, the discoverers will get a right to suggest a name for it as soon as it is recognized by the JWP; a Dubna authority said in June 2012 that it "could take up to a year" before this happens.

Famous quotes containing the word naming:

    See, see where Christ’s blood streams in the firmament!
    One drop would save my soul—half a drop! ah, my Christ!—
    Ah, rend not my heart for naming of my Christ!—
    Yet will I call on him!—O, spare me, Lucifer!—
    Where is it now? ‘T is gone; and see where God
    Stretcheth out his arm, and bends his ireful brows!—
    Mountains and hills, come, come and fall on me,
    And hide me from the heavy wrath of God!
    Christopher Marlowe (1564–1593)

    The night is itself sleep
    And what goes on in it, the naming of the wind,
    Our notes to each other, always repeated, always the same.
    John Ashbery (b. 1927)

    Husband,
    who am I to reject the naming of foods
    in a time of famine?
    Anne Sexton (1928–1974)
