In what way is the Rutherford’s atomic model different from that of Thomson’s atomic model?

An atom as a whole is electrically neutral because the negative and positive charges are equal in magnitude.
Rutherford’s atomic model- The gold foil experiments performed by Rutherford suggested that all the positive charge is located in a very small space which is 10 times the radius of an atom. Therefore, Rutherford gave a model in which electrons are revolving around the nucleus. Rutherford’s model of the atom failed to explain the stability of the atom.
Thomson’s atomic model-
J. J. Thomson suggested that electrons are embedded in a sphere of a positive charge. Thomson’s model of the atom fails to explain Rutherford’s α-particle scattering experiment in which most of the fast-moving α-particles passed straight through the gold foil.
