How was Thomson's atomic theory different from Rutherford's atomic theory?

Thomson proposed the first simple and primitive model which considered an atom to be a sphere of uniform positive charge into which the negatively charged electrons were embedded. Rutherford proposed and discovered the nature of the radioactive a, b and g rays. From that, Rutherford further concluded that an atom consists of a positively charged nucleus surrounded by electrons that move around it. The positive charge of the nucleus is due to the protons. The biggest difference then was that Thomson thought that electrons and protons were randomly placed throughout the atom, whereas Rutherford was able to theorize what kind of actual not random placement protons and electrons had.
