not so much protons (which would be a problem, but could at least notionally be deflected), but atoms.

An hydrogen atom and a proton are roughtly the same thing, right?

no a proton is a hydrogen nucleus (or at least can be seen as one) and has a charge. travelling near lightspeed you would have to worry most about uncharged atoms/molecules (because of their mass) and neutrons, neither of which can be deflected.

A proton is a hydrogen ion and isotope.
