Hi does an electron by itself have a nucleus?

Not that I know of.

Hi does an electron by itself have a nucleus?

In the standard model an electron is a fundamental particle, so it has no internal structure

 

[Nugatory]

Rutherford inferred the existence of the atomic nucleus by firing alpha particles at gold atoms. Most of the alpha particles blasted straight through as expected, but a few rebounded at sharp angles indicating that they had struck something at least as substantial as the alpha particle itself and that the atom was not a uniform cloud of stuff. No similar effect has ever been observed with electrons (and innumerable experiments over the years have involved highly energetic electron collisions); there is no reason, either theoretical or experimental, to believe that the electron has any internal structure or can be further decomposed.

Not to mention, the best and latest measurements found no electric dipole moment for the electron.
