The model represented corresponds to Thompson's model.
Atomic models
Atomic models were responsible for describing how the atom would configure itself and how it would behave.
As an example of a model we have Thompson's, known as "plum pudding".
This name is due to the description of the atom given by Thompson, who stated that the atom was a positive mass "filled" with negative charges (electrons), hence the reference to a "plum pudding".
So, the model represented by the image is that of Thompson.
