How does the plum pudding mode fit with Thomson observations?

The plum pudding model, proposed by J.J. Thomson, fits with his observations of cathode rays, which he discovered to be composed of negatively charged particles (electrons). In this model, Thomson suggested that atoms are uniform spheres of positively charged matter with electrons embedded within them, akin to plums in a pudding. This framework was an early attempt to explain the overall neutrality of atoms despite the presence of negatively charged electrons. However, this model was later challenged and replaced by the Rutherford model after further experiments revealed the existence of a dense atomic nucleus.
