The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

For now, they're known by working names, like ununseptium and ununtrium — two of the four new chemical elements whose discovery has been officially verified. The elements with atomic numbers 113, 115, ...

As of 2019, the Periodic Table of the Elements has been around for 150 years. Maybe you've felt a certain chemistry with 2019 but don't know why? Maybe it's because this year marks the 150th ...

Have we reached the end of the line of discoverable elements? Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered ...

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory are using the 88-Inch Cyclotron to help steady the famous periodic table of elements one atom at a time where it's gone a ...
