Electrons can extend our view of microscopic objects well beyond what's possible with visible light—all the way to the atomic scale. A popular method in electron microscopy for looking at tough, ...

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 ...

How to find valence electrons? Valence electrons are the outermost electrons in an atom, crucial for determining its chemical properties and reactivity. This article explains how to find valence ...

Scientists have developed a new imaging technique, tested on samples of nanoscale gold and carbon, that greatly improves images of light elements using fewer electrons. The technique can reveal ...
