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 ...

At a Scottish university, the oldest periodic table of elements was unearthed, dating back just a few years after the concept ...

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 ...

Eric Scerri, a UCLA chemistry lecturer, has written at least six books discussing the orientation of the periodic table. His office is cluttered with posters and three-dimensional models of different ...

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 ...

All matter–oceans, land, atmosphere, humans, animals, plants, food, materials, products, buildings–is made from 118 known chemical elements. These elements are ordered in the periodic table of ...

A new model rectifies the long-standing deficiencies of the electronegativity concept.

The orderly periodic table—often printed with just the chemical symbol and atomic weight of its 118 elements—doesn't quite manage to convey to nonscientists the richness of what these substances bring ...

Sorry, chemistry teachers—your periodic table posters are now obsolete. Groups of scientists in the United States, Russia and Japan had more to celebrate last week ...

The rare radioactive substance made its way from the United States to Russia on a commercial flight in June 2009. Customs officers balked at accepting the package, which was ensconced in lead ...

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 ...

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 ...
