Thomson (1856–1940) performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by many scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets …

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. http://scihi.org/thompson-electron-proof/
