I was not pleased with my previous one, as the strong nuclear force was not properly represented. I think I might have gotten it now.

The protons will repel each other if too far away, per the electromagnetic force acting between two positive charges, but if they are within the range of the "gluons" on the protons, they will be bound together. The electrons are attracted to the protons (and i think the neutrons as well, but I dont really know what to do to fix it).

I am going to try to make this as accurate as possible, and this is step one. Any suggestions would be helpful and welcome.
