Quarks and electrons?

Question

What are electrons made up of? because today my chemistry teacher told us they were made of of quarks. and i was pretty sure that only protons and neutrons were made up of quarks. and that electrons are leptons, which are fermions, which arent made up of quarks at all. im right arent i?

dan, i would give you the best answer now but i have to wait 2 hours. thanks.

Answer 1

Bingo, give yourself 2 points.

According to Wikipedia: http://en.wikipedia.org/wiki/Electron
"The electron is in the class of subatomic particles called leptons, which are believed to be fundamental particles."

According to Wikipedia: http://en.wikipedia.org/wiki/Lepton
"In physics, a lepton is a particle with spin-1/2 (a fermion) that does not experience the strong interaction (that is, the strong nuclear force). The leptons form a family of elementary particles that are distinct from the other known family of fermions, the quarks."

According to Wikipedia: http://en.wikipedia.org/wiki/Quarks
"In particle physics, the quark (pronounced IPA: /kwɔː(r)k/) is one of the two basic constituents of matter (the other is the lepton). It is quarks that make up protons and neutrons, with there being exactly three quarks within each kind of particle."

So print this out and educate your teacher. Quarks are LIKE electrons; fundemental particles, but quarks don't make electrons.
