Neutron, Proton, Electron are Questionable as the basis of the Atom as Proton, Neutron, Electron can be seen as reactions with Radium by British Scientists- We can return to a Mysterious Cloudy View of the Atom
Neutron discovered by James Chadwick could be questioned as alpha causes particle emission reaction product. Neutrons may not be fundamental but rather a reaction product. Electron discovered by JJ Thompson could be questioned as particles deflect to positive plate are possibly a gas or gravity effect? Proton could be questioned as radium effect with Au or Gold not fundamental.
