Four new elements have been added to the standard periodic table and their creators from Japan, Russia and the United States will now come up with permanent names and symbols for them.

An entry on the periodic table of the elements filled in and autographed by physics professors Joe Hamilton and A. V. Ramayya is displayed at Vanderbilt University in Nashville, Tenn.

All four elements are not found in nature, and were synthetically created in laboratories. Until now, these elements had temporary names and symbols on the periodic table as their existence was ...

The elements, discovered by researchers from Japan, Russia, and the United States, are known by their atomic numbers of 113, 115, 117, and 118. They will be given permanent names soon, according ...

The periodic table currently has 118 chemical elements (SN: 11/30/16). The five heaviest elements were all produced using a beam of calcium-48. That’s a variety, or isotope, of calcium with 28 ...
