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 ...

A new technique could one day provide the most precise measurement yet of the roundness of an electron, scientists say. That measurement, in turn, could help scientists test extensions of the Standard ...

Valence Electron Examples: Valence electrons play an important role in the field of chemistry, affecting how atoms interact and bond with each other. These outermost electrons are responsible for ...

The standard model (SM) of particle physics describes how the Universe works at a fundamental level. Even though this theory has proven to be very successful over the past 50 years, we know it is ...
