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.

(N/A) Ravi possesses the following qualities:
$(i)$ Imaginative: He visualizes abstract concepts.
$(ii)$ Creative: He relates scientific models to real-life examples.
$(iii)$ Curious: He seeks to understand the logic behind analogies.
$(b)$ The limitations of Thomson's model are:
$(i)$ It failed to explain how the positive and negative charges are arranged within an atom so close to each other without neutralizing one another.
$(ii)$ It could not explain the results of experiments performed by other scientists,such as Rutherford's alpha-particle scattering experiment.
