More than a thousand different versions of the periodic table have been created since Dmitri Mendeleev drew the first 150 years ago – but why is one version more familiar to us than practically every ...

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 missing ...

But the periodic table didn’t actually start with Mendeleev. Many had tinkered with arranging the elements. Decades before, chemist John Dalton tried to create a table as well as some rather ...

The periodic table is part of the bedrock of chemistry education. Students use it to look up values like an element’s atomic mass, and it serves as a visual reference for the trends in physical ...

The Committee on Chemists with Disabilities is planning to showcase 50 braille periodic tables in 50 states by their 50th anniversary ...

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, ...

James Tickner does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

Every field of science has its favorite anniversary. For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of ...

We see a lot of clocks here at Hackaday, so many now that it’s hard to surprise us. After all, there are only so many ways to divide the day into intervals, as well as a finite supply of geeky and ...

To expand the periodic table, it might be time to go titanium. A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged ...

The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits. By Siobhan Roberts When Sir Martyn Poliakoff, a ...
