What are electrons made of?

Answer 1

Previous answer submitted was "electrons are made up of quarks"

They most certainly are not! Electrons are leptons. Leptons are NOT made of quarks (the proton and the neutron are barions and thus made of 3 quarks). Fermions are believed to be fundamental meaning they are not made up of any smaller particle. However, some research has shown that they may be made up lesser charged particles "quasi-particles" which are a mixture of boson and fermion called ANYONS (bosons are massless (like light patricles) and fermions and leptons have mass)

[This is quantum physics by the way, not chemistry]

_________________________________________________________________

The above answer is not exactly correct either (I think he wanted to say are electrons made of matter).

Electrons are made up of something, we simply don't know the nature of this matter. But electrons as fundamental particles are not divisible in other smaller particles.

Answer 2

Electrons are considered elementary particles, which means they are not made up of any smaller components. They are a fundamental building block of matter and are found in the outer shells of atoms, carrying a negative charge.

Answer 3

metal and steel
