Question

Which hypothesis of Thomson's atomic model was later found to be not true by Rutherford and why? (5 points)

Answer 1

Answer:

Explanation:

In 1911, Rutherford showed that Thomson's model was "wrong": the distribution of positive and negative particles was not uniform. Rutherford showed that the atom contains a small, massive, positively charged nucleus. He also agreed with Nagaoka that the electrons move in circular orbits outside the nucleus

thank you..

Answer 2

• Thomson stated that the atom looks similar to plum pudding.

    Therefore his model was also called as plum pudding model.

   According to him, the negative charge is spread throughout the positive  

   charge.

But, this was found to be a wrong hypothesis.

• Rutherford told that the positive charge is concentrated in the center of the atom in the nucleus.

        The electrons move around the nucleus in fixed orbits.

      Every orbit has its own energy. The orbit closest to the nucleus has lesser

      energy.
