What are found in the nucleus and have a positive charge?
At extremely short nuclear ranges, these particles engage in the

It would have made much more sense to designate the nuclear charge as negative and the electronic charge as positive. No would complain save for a few wacko particle physicists. These days the negative charge of the electron is hallowed by usage.
