Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding.

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

IN a letter to NATURE of November 25 last Dr. Norman Campbell discusses the problem of the possible consistency of the assumptions about the motion and arrangement of electrons in the atom ...

Artistic representation of an artificial atom (shown as an atomic structure) implemented in a superconducting circuit interacting with its mirror image created by a short circuit. This configuration ...

University of Queensland researchers have made a breakthrough in muonic atom ... just like electrons, forming muonic atoms, but because they are much closer to the nucleus, they see its structure ...
