LIVERMORE — By firing atoms of metal at another metal, Russian and American scientists created an element — No. 118 on the periodic table — that is the heaviest substance known, the scientists ...

A U.S. and Russian team said Monday that it had created element 118, the heaviest known to date. It is the fifth ultra-heavy element produced by the team at Lawrence Livermore National Laboratory and ...

In a rare public display of the scientific process at its messiest, physicists at the Lawrence Berkeley National Laboratory retracted yesterday their spectacular 1999 claim of having discovered two ...

New research suggests that the periodic table may once again reach 118. A team of nuclear chemists from the United States and Russia has announced the brief appearance of the unnamed element, the ...

The first 117 elements on the periodic table were relatively normal. Then along came element 118. Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest element ...

After claims of its discovery were retracted in 2002, a new team of researchers says it has produced a few scant atoms of the heaviest element yet, called simply element 118 after the number of ...

For the second time in seven years, researchers say they have made the heaviest chemical element ever — the exotically titled ununoctium, or element 118. The evidence comes in the form of specific ...

Many people have done experiments in science classes that cause an explosion by reacting hydrogen and oxygen. However, when it comes to dangerous elements and rare elements that are difficult to ...
