The NEW chart has added elements & many definitions have been added/updated
To use the table; hold your mouse
over the specific Element and the "alt" tag will show the symbol
and the name of the Element. Click [that Element], and the link goes to
an "anchor" on [this page].
Use your "browser-back" button to reutrn to the top of the page,
or click the -top-
link between the element listings.
NOT ALL Elements have anchored links right now. This table
in use is was created by JSV.
More information and 'links' to resources for better understanding what's
known as
"Element 115" (or) "Uup - Ununpentium", wil be added.
In the works, is a whole page of links about [this element].
For
now, try using this "Google search"
If you want to offer/submit any resources that could or
may help,
regarding ANY of the Elements, Please

On June 7, 1999, scientists working at the U.S.
Department of Energy's Lawrence Berkeley National Laboratory
announced the discovery of element 118. The scientists attempted to make
element 118 by smashing
krypton ions into a lead target with a machine called a cyclotron. Three
atoms of element 118 were thought
to have been created during 11 days of experimentation. The
Lawrence Berkeley scientists,
as well as other scientists at other labs, attempted to confirm the discovery
of element 118.
Duplicate experiments conducted at other labs failed to produce any
sign of element 118.
A careful re-analysis of the original data using different software also
failed to find any evidence of element 118.
As a result of these failures, the Lawrence Berkeley scientists retracted
their claim on July 27, 2001.
