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 ...

They cross orbital electron clouds in times shorter than one billionth part of a nanosecond (i.e. 10 -18 s). In quantum mechanics, problems in which interactions are so short are treated by finding a ...

(Nanowerk News) 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 ...
