|What are electrons made of?
You've asked a great question! An electron is
not "made up" of anything; it is indivisible and
cannot be broken down into other particles.
Particles that are indivisible that cannot be
broken up into other things are said to be
"elementary particles." They are the building
blocks of matter.For instance, a proton is made up
of two "up" quarks and one "down"quark, these
quarks, like an electron are also elementary
particles and are not "made up" of smaller
particles. There are 12 such elementary particles,
which include electrons. These 12 are talked about
on this website:matter
has an awesome video which talks more about these
building blocks of nature. I encourage you to look

As far as we can tell, electrons are not made
from anything else. They are a fundamental
particle.Then again, people used to think that
atoms were fundamental particles, too, until we
discovered they were made from smaller particles
(protons, neutrons, and electrons). But we don't
have any evidence to suggest electrons are made
from anything smaller.
So far as is known, electrons are elementary
particles. They are not composed of smaller parts.
