Question: Is there a specific shape to electrons?

Susan Cartwright answered on 20 May 2020:

Not to electrons as such, no. In fact, we have never been able to detect that the electron even has a finite size: it interacts as a simple point-like mass with no dimensions. However, as entities described by quantum mechanics, electrons are described by quantum-mechanical “wavefunctions”, which describe the probability of finding the electron at any given place. If the electron is bound in an atom, these probability distributions do have definite shapes, and they are by no means all spherical – see the diagram at https://socratic.org/questions/could-someone-please-describe-the-shapes-of-electron-density-maps-for-s-and-p-or But note that these are the shapes of the volumes where you might expect to find the electron – not the shape of the electron itself.
