W-FEB -super heavy elements

dec 2011, 1st
The International Union of Pure and Applied Chemistry — the scientific body that is the keeper of the list of elements — unveiled Thursday the proposed names for elements 114 and 116: flerovium (atomic symbol Fl) and livermorium (atomic symbol Lv).

• the two elements had indeed been created in collaborative experiments by the Joint Institute for Nuclear Research in Dubna, Russia, and the Lawrence Livermore National Laboratory in Livermore, Calif.

The process of coming up with what to call them was nearly as arduous.

•  if the chemistry union rejects a name, that name cannot be proposed for any subsequent element discoveries.
•  Livermorium is, of course, named after the laboratory and city where it is located.
• Dubna has already been enshrined in the periodic table with dubnium (element 105), so the Russians chose to honor Georgi N. Flerov, the founder of the research institute.

element 110, 111,112,114,116 are unstable and lasrge.
due there unstability its difficult to worlk on them,
they are not found in nature--hencse they are called super heavy or transuranium.
