Answer:

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

Explanation:

The hypothesis of J.J Thomson's atomic model later found to be false was that atoms contain tiny negatively charged particles or electrons and are uniform with positively charged particles.

Thomson's atomic model hypothesis

J.J. Thomson's carried out his experiment with cathodes tubes which showed that;

  • Cathode Ray's and charge are intrinsically linked together.
  • The cathode rays were negative.
  • Atoms contain tiny negatively charged subatomic particles or electrons.

But Niels Bohr carried out his own experiment and discovered that J.J Thomson was wrong because;

  • The atom contained positively charged particles surrounded by orbiting electrons and
  • The positive and negative particles was not linked together or uniform.

Hence, the hypothesis of J.J Thomson's atomic model later found to be false was that atoms contain tiny negatively charged particles or electrons and were not uniform with positive charged particles.
