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 ...

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 ...

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for ...

An Ionic bond is formed when one of the atoms can donate electrons to achieve the inert gas electron configuration and the other atom needs electrons to achieve the inert gas electron configuration.

Melvyn Bragg and guests discuss the discovery of this atomic particle in 1897 and what our growing knowledge of electrons has revealed about our world and may yet reveal. Show more Melvyn Bragg and ...

We can now detect single electrons with the resolution of a few trillionths of a second, and this could prove essential for building a new generation of quantum electronic devices. Traditional ...
