In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary particles ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue examines how atomic structure determines reactivity. Meet Theo Gray, chemist and author, who ...

The periodic table has been a vital foundational tool for material research since it was first created 150 years ago. Now, researchers add an entirely new dimension to the table, offering a new set of ...

A group of researchers from Ehime University investigated valence electron configurations using light, expanding on prior studies of superconductors and quantum spin liquids. The findings were ...
