The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...

When we were in school, they always told us we can’t see atoms. If you have an electron microscope, then they were wrong. [AlphaPhoenix] has access to a scanning tunneling transmission electron ...

The first example of a stable, doubly oxidized carbene has been made by chemists in pursuit of octet-rule-defying molecules. Most carbon atoms possess 8 valence electrons, which is why they are said ...

Three scientists won the Nobel Prize in physics on Tuesday for studying how electrons zip around the atom in the tiniest fractions of seconds, a field that could one day lead to better electronics or ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...
