Answer:
d. protons and electrons have different charges.
Explanation:
Thomson Model : As per Thomson model of electron electrons are randomly distributed inside the atom and whole atom is considered as a positively charged sphere.
So in this model we did not discuss about the nuclei of the atom but we know in this model that atom consist of two type of charges (i) charge on electrons is negative (ii) charge on the rest of the atom is positive.
Rutherford Model : As per his theory he explained by his gold foil experiment that there must exist a nuclei which is very small part of the atom and whole positive charge of atom lie inside the nuclei
While electrons have negative charge and all electrons revolve around the nuclei in definite orbit.
So here correct answer would be
d. protons and electrons have different charges.
