Wrong Connectivity: The order in which atoms are connected matters. For example, nitrous acid (HNO₂) has the structure HONO, ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

Water (H₂O): Oxygen shares one electron with each of the two hydrogen atoms. Each hydrogen atom contributes one electron, ...

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 distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...

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 ...

The resolution of electron microscopes is superior to that of optical microscopes because high-energy electrons have a much shorter wavelength than light. In the 1970s Albert Crewe at Chicago ...

Adapting a detector developed for space X-ray observation, researchers have successfully verify strong-field quantum electrodynamics with exotic atoms. An international collaboration of researchers, ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
