The question is from a student in Mrs. Alexander's seventh-grade science class at Smithton Middle School. A: "An electron is both a wave and a particle. You cannot pinpoint exactly where it is as any ...

For the first time, scientists have used ultrafast X-ray flashes to take a direct image of a single electron as it moved during a chemical reaction. In the new study, published Aug. 20 in the journal ...

Can scientists image the motion of electrons inside atoms? It’s a challenging problem, but solving it would help us develop a more complete understanding of things like chemical reactions and the ...

All the elements in the Periodic Table are made from different atoms, and the structure of these atoms results in a gamut of phenomena from radioactive decay to nuclear power. When you purchase ...

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 ...
