Two new highly radioactive elements added to the Periodic Table 
Scientists from the international overseeing committees of physics and  
chemistry have _added two new elements_ 
(http://www.bbc.co.uk/news/science-environment-13699575)  to the  periodic table. 
The _still-unnamed elements_ 
(http://www.wired.com/geekdad/2011/06/new-heavy-elements-need-geeky-names/)  114 and 116  are both extremely radioactive 
and, with respective atomic mass unit values of  289 and 292, are now 
heaviest table-members, taking the place of copernicium and  roentgenium. 
The discovery of both elements has been credited to the Joint Institute for 
 Nuclear Research in Dubna, Russia and Lawrence Livermore National 
Laboratory in  California. The collaborative parties have proposed the name 
flerovium for 114,  after Soviet scientist Georgy Flyorov, and moscovium for 116, 
after the region  in Russia. 
According to _Wired_ 
(http://www.wired.com/wiredscience/2011/06/new-heavy-elements/) :

The two new elements are radioactive and only exist for less than  a second 
before decaying into lighter atoms. Element 116 will quickly decay  into 
114, and 114 transforms into the slightly lighter copernicium as it sheds  its 
alpha particles.
_A joint effort_ 
(http://www.npr.org/templates/story/story.php?storyId=137058735)  by the  International Union of Pure and Applied Chemistry (IUPAC) 
and the International  Union of Pure and Applied Physics (IUPAP) required 
three years to approve the  addition. Other periodic table hopefuls 113, 115 and 
118 are still pending  approval. 
The elements are temporarily labeled ununquadium and ununhexium, pending  
final naming. 
A full report of has been published in the journal _Pure and Applied 
Chemistry_ (http://iupac.org/publications/pac/asap/PAC-REP-10-05-01/) .
