Are subatomic particles spherical in shape?

Best Answers

I'd say spin 1/2 charged particles such as electrons are cylindrical, if you consider only electromagnetism. Seriously, because I have never seen a spherical solution for the self-consistent equations describing a Dirac spin 1/2 particle with an EM field. Ok, if you include the weak force, then you can find a spherical solution. read more

Textbooks and the like render them as sphere because you can't see a point and their influence is felt the same in all directions. But they don't have shapes in real life because they don't have volume. Only larger structures with arrange subatomic particles have volume, e.g. protons. read more

For water drop, it's because of the surface tension. At the spherical shape, the drop has smallest surface area so its tension energy is at the lowest of all. For atronomical objects, the cause is nearly the same: At spherical shapes, they all have smallest gravitational potential. read more

For composite particles, the constituents can do different kinds of bizarre behaviours and also we have wave-particle duality and no shape is defined for composite particles. But for elementary particles, they are just considered to be points. read more
