International guidelines for choosing a name say that new elements "can be named after a mythological concept, a mineral, a place or country, a property or a scientist," according to the IUPAC. Karol says that researchers will continue seeking "the alleged but highly probable 'island of stability' at or near element 120 or perhaps 126," where elements might be found to exist long enough to study their chemistry. It is in the electron behavior, perhaps better called electron psychology, that the chemical behavior is embodied." "The eighth period should be very interesting because relativistic effects on electrons become significant and difficult to pinpoint. "There are a couple of laboratories that have already taken shots at making elements 119 and 120 but with no evidence yet of success," he said in an email. With the additions, the bottom of the periodic table now looks like a bit like a completed crossword puzzle - and that led us to get in touch with Karol to ask about the next row, the eighth period. Each of the discovering teams have now been asked to submit names for the new elements. The elements' temporary names stem from their spot on the periodic table - for instance, ununseptium has 117 protons. The working group includes members of the International Union of Pure and Applied Physics. "A particular difficulty in establishing these new elements is that they decay into hitherto unknown isotopes of slightly lighter elements that also need to be unequivocally identified," said Paul Karol, chair of the IUPAC's Joint Working Party, announcing the new elements.
The seventh period of the periodic chart is now complete, thanks to the addition of four new elements. That collaboration has now discovered six new elements, including two that also involved the Oak Ridge National Laboratory in Tennessee. Three other elements were discovered by a collaborative effort among the Joint Institute for Nuclear Research in Dubna, Russia, the Lawrence Livermore National Laboratory in California. Element 113 was discovered by a group at the Riken Institute, which calls it "the first element on the periodic table found in Asia." The elements were discovered in recent years by researchers in Japan, Russia and the United States. The additions come nearly five years after elements 114 (flerovium, or Fl) and element 116 (livermorium or Lv) were added to the table. With the discoveries now confirmed, "The 7th period of the periodic table of elements is complete," according to the IUPAC. The elements with atomic numbers 113, 115, 117 and 118 will get permanent names soon, according to the International Union of Pure and Applied Chemistry.
