During Beta decay, an electron is shot out of the nucleus and a neutron changes into a proton. A proton is a up,up, down quark combination and a neutron is an up, down, down quark combination. Is the electron coming from the neutron and if so then must an electon be smaller that a quark since both Up and Down quarks have about the same rest mass? Are electrons a type of "string" from string theory?

It's too early to speak of the size of a quark, since no one has seen one. If size is even a meaningful descriptor, it seems likely that it is no larger than a proton or neutron. Hadronic string theory doesn't even consider leptons like the electron, but superstring theory (as most current string theories) consider all matter. See the reference for what is inferred about quark masses and why.

first of all, opposite to what some solutions have declared, electrons are truly no longer made from quarks. cutting-edge information is that electrons and quarks are both element-like products. by technique of firing electrons at one yet another you will be able to come back up with an top reduce on the radius of the electron, yet so a concepts no try has been whose effects are inconsistent with a nil-radius merchandise. Quark dimensions might want to be in addition probed by technique of colliding baryons at severe energies, or firing electrons at baryons and scattering from human being quarks. back, no measurable length has ever been discovered for the radius of a quark. So, there is no experimental data that quarks are smaller than electrons, or that electrons are smaller than quarks. at present, we've not something that proves they have any length in any respect.

No one has ever determined the size difference (due to no quarks ever being kept in isolation long enough- see CERN) and the electron is still thought of as singular (no smaller components). You are correct in assuming the relation in string theory, I know teachers hate it but use wikipedia

quarks are the smallest
