Is electron the smalest particle? as there is no limit for the biggest particle say universe, there will not be a least size for a matter no?

as we could not break electron we r saying electron is the smallest part but if there is a method to break ,then it will not be smallest no?

We do not yet know which particle is the smallest, as there could be many particles we do not know about.

Each time in history we have thought we have found the most basic matter, we have found something smaller - like neutrons and protons proved to be built out of quarks.

However the electron is currently thought to be basic, that is, not have internal structure. The electron is not the smallest known entity however.

According to theories such as string theory there are tiny strings vibrating that are the most basic of all and thus smaller than any current particles by many many times.

However it is thought there is a fundamental limit to how small we can go, with the smallest unit of space perhaps being the Planck length, therefore if this is the smallest unit then that would also be the fundamental smallest length for a particle of matter.
