The attempt itself to visualise is actually a huge problem..
Because, in order to see clearly the electron inside atom, you have to shine a ligh on it, right? And that light must be of a short wavelength.. to be able to see clearly wher ethe electron is..
And our "visualization" firmware in our brains totaly relies on the assumption (almost fact!) that the light reflects from object without changing the object itself.... which can't be further from the truth.
The moment the light is supposedly "reflected" from the electron (which never happens in reality, thi is experimental fact), it is not there any more. So what you see is NOT what you get
