Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) are credited in the discovery of 16 of the 118 known elements. Now they’ve completed the crucial first ...
At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...
