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, resulting in oxygen having a total of 8 electrons in its valence shell (2 from ...

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 ...
