What are the limitations of Rutherford's model of the atom?

During class,Ravi's teacher was teaching about Thomson's model of an atom,stating that an atom is electrically neutral,i.e.,it contains equal positive and negative charges,and that an atom consists of a sphere of positive charge in which electrons are embedded like plums in a pudding. Ravi wondered how his teacher related Thomson's model of an atom to a plum pudding,and he imagined that just as dry fruits are embedded in a Christmas pudding,electrons are embedded in a sphere of positive charge.
$(a)$ According to you,what kind of qualities does Ravi possess?
$(b)$ What are the limitations of Thomson's model?

$(a)$ Why are anode rays called canal rays?
$(b)$ Mention two postulates of $J. J.$ Thomson's model.
$(c)$ Compare the properties of protons and electrons.

On the basis of Rutherford's model of an atom,which subatomic particle is present in the nucleus of an atom?

What do you think would be the observation if the $\alpha$-particle scattering experiment is carried out using a foil of a metal other than gold?

In the Thomson's model of atom,which of the following statements are correct?
$(i)$ The mass of the atom is assumed to be uniformly distributed over the atom.
$(ii)$ The positive charge is assumed to be uniformly distributed over the atom.
$(iii)$ The electrons are uniformly distributed in the positively charged sphere.
$(iv)$ The electrons attract each other to stabilize the atom.
