Do All Protons Have the Same Number of Quarks?
September 28, 2017 at 4:25 pm
1. If so, is there a law or constant that explains why the strong force only allows a certain number of quarks to bind together?
2. If not, does the number of quarks in a proton affect its mass?

Yes they do.
All electrons are absolutely identical to each other too.

The number and variety of quarks determines if it's a proton or something else.

One Quark per proton is the limit.

I've changed over to metric.

Not all electrons are identical.
You have "Electric Avenue".

There's also very spherical, as-in, (maybe) perfect spheres, despite being di-pole.

Hi!
Yes and no - there are three quarks which make up its fixed inventory, but on top of that, quark-antiquark pairs pop in and out of existence constantly. The net number if you take the difference of quarks and antiquarks is exactly 3 though.
Wjy 3 exactly? Because the strong force is so strong, stable isolated particles need to be color neutral to exist. The symmetries of the strong force have the property that it is not possibe for 4 or 5 quarks to be color charge neutral. This can be explained by the mathematical structure of the strong interactions which are governed by an SU(3) symmetry group - if you want to get technical.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
