Not really, since that particular combination is a hydrogen atom. A neutron consists of three individual quarks, one blue, one red and one green. The quark colors refer to the charge of a quark, and the three colors yeild a net charge of zero, making the neutron the particle of choice for triggering nuclear fission and fusion, since it has mass but no charge. If you tried to use a nearly equally massive proton to crash into the nucleus of an atom and trigger a chain reaction, it would never hit its target, because the like charges would repel each other.
