What are the strengths and weaknesses of rutherford's nuclear model of the atom?

Rutherford explained the observations made by Geiger and Marsden where alpha particles are scattered through much larger angles than expected. Rutherford explained this using an electrostatic repulsion model by saying that atoms are mostly empty space with a small, dense, positively charged nucleus that repelled and deflected the positively charged alpha particles. This is essentially the same as the modern atomic theory, and therefore, the strength of the model. If you call it a weakness, Rutherford didn't address the arrangement of electrons in atoms.
