Answer:
John Dalton
Explanation:
J.J. Thompson’s cathode ray experiment proved that Dalton’s atomic theory was incorrect,
Dalton proposed that atoms are indivisible and they are the smallest part of a substance. But Thompson’s cathode ray experiment showed that atoms are made up of negatively charged particles. Option B is correct.
Option A is incorrect. Neils Bohr gave the atomic model after J.J. Thompson and he explained the quantization of electron energy.
Option C is incorrect. Erwin Schrodinger proposed that electrons move in electron clouds, electrons do not have a definite position and there is a probability of finding electron in space.
Option D is incorrect. James Chadwick discovered the neutron.
