• Each of the atoms of Element 118 survived for less than 1 / 10, 000 of a second before decaying radioactively into an atom of a second new element, Element 116, with 116 protons and 173 neutrons in its nucleus.
• Several days later, he began telling colleagues that he had observed three instances of what appeared to be the decay of a 118 nucleus to form element 116 ( also never before observed ) then 114, 112 . . . all the way down to 106, seaborgium.
• This year, another major lab trying to create elements, Lawrence Berkeley National Laboratory in California, forged the heaviest element yet, 118, and when it decayed, it morphed into element 116, then an isotope of 114 with even fewer neutrons than Dubna's.
• The Berkeley experimental team, headed by Dr . Kenneth Gregorich, measured the atom's decay into Element 116, then 114, then 112 and on down to 106 _ an artificial element that was recently named seaborgium in honor of the late Dr . Glenn Seaborg, the chemist who discovered plutonium.
• Sifting through the data, they concluded that they had found three collisions in which, in a rapid chain of events, a krypton atom and a lead atom fused together into Element 118 _ that is, an element with 118 protons _ and then, within one ten-thousandth of a second, decayed to Element 116 ( also a never-before-seen element ), then 114, then 112 and on down to 106.
