The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

New force distributions revealed by the calculations, on top of the probability map of finding a quark in the proton. Joshua ...

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 ...

In the vast expanse of space, where stars are born and planets take shape, one molecule plays a crucial role in interstellar ...
