Hope you are particular about the proton and not anit proton. The beauty is that the number of protons ie atomic number is the code for knowing the element. So 7 is the door number for nitrogen. Hence it has 7 protons. If one proton right from nitrogen nucleus is taken out then nucleus becomes that of carbon. If one proton is added then it becomes 8, so it is oxygen atom.

Moreover nitrogen atom does exist as monoatomic molecule. It always exists as diatomic molecule. That is nitrogen gas.
