>116, 118 Berkeley USA - 1999
Hi
This announcement of new heavy element was retracted because the claim is based on fabricated / fake data.
The official heaviest element is Darmstadtium (111) from Darmstadt, German.
There are claims about 112, 114, 116, but IUPAC have not make any decision about the new elements.
