Hence the alpha particle is deflected by electric . Neutrons generally result from nuclear reactions, such as nuclear fission (as in nuclear reactors and fission-based nuclear weapons) and charged-particle activation of target atoms (as with some accelerator-produced radioisotopes). the electron surrounding the nucleus revolves around it in a circular path with very high speed. Thomson's plum pudding model viewed the atom as a massive blob of positive charge dotted with negative charges. On the other hand, if it passes through at a fair distance from this mass, then there would be no deflection and it would simply pass through.
