For the last fifty or so years, the periodic table has been incomplete. Elements after uranium on the periodic table have been synthesized for the past few decades, but there were always a few ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

This is the second part of a three-part series written by Carolyn Krause. Many of the elements were synthesized using an Oak Ridge reactor.

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the transuranium element berkelium. According to a new study, the electronic signature of ...

The story of the last element to be discovered out of the first 92 catalogued in the periodic table is told by Eric Scerri, who reminds us that technetium can be found a little closer to home than ...
