Scientists at Berkeley Lab have used a titanium beam to make atoms of element 116. Not only does this represent a new way to make the super rare element, but it stands as a proof-of-concept that they ...

Element 112 did not invite a lot of interest when theoretical nuclear physicists predicted the famous island of stable superheavy elements — elements that have a number of nucleons that leads to ...

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 ...
