Dear Baba
On the basis of Heisenberg's uncertainty principle, it can be shown as to why electron cannot exist within the atomic nucleus. The radius of the atomic nucleus is of the order of 10-15 m. Now, if the electron were to exist within the nucleus, then the maximum uncertainty in its position would have been 10-15 m.



Mass of electron, m = 9.1 x 10-31 kg, Dx =1 x 10-15 m.

The value of uncertainty in velocity, Dv is much higher than the velocity of light (3.0 x 108 ms-1) and therefore, it is not possible. Hence an electron cannot be found within the atomic nucleus.
All the best

hi garg
because if you consider the electron in nucleus it will be the thomsons model and this model cannot explain the stability of atom and also the advantages of bohr's model

well the maximum energy of emission of em waves from the atom(like beta rays) is 7MeV.if the electron were to exist in the nucleus,then the energy of the electron would become around 20MeV,which means that the energy of the emission show be higher.so electrons can’t exist in nucleus,all this data is experimental.
