WebOne hundred years ago, it was discovered by Rutherford that most of the atoms were empty. After that, Niels Bohr presented a more refined atomic model. Bohr’s atomic model is very close to the atomic model that can be seen these days. In Bohr’s atomic model, electrons are in a given orbit. WebApr 23, 2014 · Explanation: Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles.
