In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary particles ...

No one will ever be able to see a purely mathematical construct such as a perfect sphere. But now, scientists using supercomputer simulations and atomic resolution microscopes have imaged the ...

Free electrons moving through space are fundamental and indivisible: they are not built up of smaller particles, in contrast with protons and neutrons. However, within materials, interactions among ...
