Are there such things as an electron wtih -2 on it? Or say a proton with +2
No, because a proton is defined to have a charge +1. If it were to have a charge +2, it would by definition no longer be a proton.
There are no particles in the standard model with charge +2 or -2.
Yes I understand that a proton is only +1 I just forgot the name for that branch of particles.
But yeah i was wondering if there was a model which I guess there is not as you say.
If it had a -+2, it wouldn't be a proton. Protons have a specific amount of charge, and that value is deemed 1. So it's that 1 that defines what a proton is.
the Δ++ resonance has a charge +2. whether you want to call it a particle or not, now that s a different question.
