The International Union of Pure and Applied
Chemistry (IUPAC) approved the addition of flerovium and livermorium to the
periodic table of elements. The two new elements were discovered during
collaborative research carried out by scientists from the Lawrence Livermore
National Laboratory in the United States and the Joint Institute for Nuclear
Research in Russia. Flerovium (atomic symbol Fl) is an
element with an atomic number of 114 and an atomic weight of 289. The new
element was named after Georgiy N. Flerov (1913 –1990), a renowned physicist
who founded the Joint Institute for Nuclear Research in Dubna, Russia.
Livermorium (atomic symbol Lv) is an element with an atomic number of 116 and
an atomic weight of 293.The new element was named in honor of the Lawrence
Livermore National Laboratory in Livermore, California, USA. The addition of
flerovium and livermorium brings the total to 118 elements listed on the periodic
table. But not all of these elements have been proven to exist with the rigor
that the scientific process demands
