Question

State the limitations of jj thomson's model of an atom in hindi

Answer 1

The limitations of J.J Thomson's model of an atom are:

1. J.J Thomson's model of the atom could not explain the results of Alpha particle scattering experiment carried out by Rutherford.

That is J.J Thomson's model of the atom could not explain why most of the positively charged Alpha particles pass Straight through the gold foil ,a few Alpha particles are deflected through small and large angles, Whereas a very few Alpha particles completely rebound on hitting the gold foil and turn back on their path.

2. J.J Thomson's model of the atom was just based on imagination it did not have any experimental evidence in its support like the Rutherford's Model of the atom.

sorry could not write in hindi

Answer 2

hey!!

_____

defination:-

__________

According to J.J Thomson's model of an atom an atom consists of a positively charged sphere with electrons embedded in it.

However, it was later found by the Rutherford that the positively charged particles reside at the centre of atom called the nucleus and the electron revolve around the nucleus.

Limitations of Thomson’s Atomic Model:-

________________________

• Thomson’s atomic model failed to explain how the positive charge holds on the electrons inside the atom. It also failed to explain an atom’s stability.

• The theory did not mention anything about the nucleus of an atom.

• It was unable to explain the scattering experiment of Rutherford.

• It did not have any experimental evidence in its support.

hope help u!!!
