The electron is, as far as we know, fundamental; it's not made up of smaller particles.
positron
the electron particles make up the mostr mass
sub-atomic particles are within the atom (and remember, atoms are everywhere): the electron, proton and neutron are all sub-atomic particles, but there are even smaller particles (and anti-particles) called quarks that make up the proton, neutron and electron.
The three subatomic particles that make up an atom, from largest to smallest, are neutrons, protons, and electrons.
The smallest particles that have been discovered and that don't only exist in theory are the quarks. They are what make up protons, neutrons, all kinds of baryons, and a few other categories of particles. But there is a theory of smaller particles that make up quarks, electrons, and other particles that were previously believed to be fundamental (But, again, these particles only exist in theory). These particles are to be called "rishons" if discovered.
These subatomic particles are generally considered the building blocks of atoms. The electron is an elementary particle, while the proton and neutron are composite particles that are made up of quarks. Links can be found below for more information.

The electron.

sub-atomic particles are within the atom (and remember, atoms are everywhere): the electron, proton and neutron are all sub-atomic particles, but there are even smaller particles (and anti-particles) called quarks that make up the proton, neutron and electron.
These particles are: neutron, proton, electron.
Protons, neutrons and electrons. There are other particles that in turn make up these particles [but that was not the question]
Proton, neutron and electron At a lower level up quark, down quark, and electron
A electron(s) in a orbital around a nucleus made of protons and neutrons.
Nucleus, which contains protons and neutrons Energy Shell/Electron Cloud, which contains electrons

Protons, neutrons and electrons The particles themselves are made up of smaller particles (quarks), bar the electron which is believed to have no sub-particles and therefore is believed to be elementary
atoms consist of even smaller particles than its self, these particles are called subatomic particles, they are the electron (negatively charged) the proton(positively charged) and the neutron (no electrical charge). while the proton and the netron make up the nucleus of the atom the electron is around the outside of the atom.
