Normally, a carbon atom shares all four of its valence electrons to create four bonds with other atoms (tetravalent carbon).

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

With a precise understanding of the valence electron density distribution ... They successfully extracted the electrons within the carbon double bonds and clearly observed differences between ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close ... When the plastic strip is rubbed on the skin, electrons from the ...

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 ...
