Why was the Thomson's Model of an atom failed?
(i) It could not explain the screening of negative charges from that of positive
(11) It did not tell about the presence of electrons
(ii) It did not give an idea about the discrete energy levels
(iv) It explained the atom as a whole to be electrically neutral
Choose the correct option from the following:
(a) Only (iii)
(b) Both (i) & (iii)
() Only 0
(d) Both (ii) & (iv)

option a). it could not explanation the screening of negative charges from that of positive.
Details about Limitations:
Limitations of Thomson’s atomic model.
It failed to explain the stability of an atom because his model of atom failed to explain how a positive charge holds the negatively charged electrons in an atom.
Therefore, This theory also failed to account for the position of the nucleus in an atom
Thomson’s model failed to explain the scattering of alpha particles by thin metal foils
No experimental evidence in its support
Although Thomson’s model was not an accurate model to account for the atomic structure,
