This is what a basic proton looks like (it has three quarks and an electron):
Q + Q + Q (2+ & 1-) //\\ (E)
This is what its quarks looks like:
(++) + (–) + (++) //\\ (–) + (++) + (–) //\\ (++) + (–) + (++) //\\ (–)
Each pair of charges is a sub-quark; each charge a quarklet. Electrons are free sub-quarks. A proton has five positive sub-quarks and four negative; its electron is its fifth negative- thus, neutrality. This diagram therefore takes matter down two levels…
Note: the main objection to a compound quark is that it’s too small not to be a point. This doesn’t apply here because each “point” also has two positive-negative cancelations which create standing waves around them. Compounds exist but two-thirds of each is intangible…
