Discovered radioactivity
Uranium Expirement -
Had the Cathode Rays tube to help in experiment
discovered the Electron, and the fact that atoms are not solid -
Discovered the nucleus is made of protons surronded by electrons
-
Determined teh charge and the mass of a nuetron
-
Alpha particle + nuetron = scattered
-
Electrons are on fixed paths
-
Discovered Isotopes mass, Spectometer
-
The quantum Model; probability of an Electron path by math electrons
-
evidence towards the existence of Nuetrons
-
Denied the atomic theory. thought that everything was made up of Earth, Wind, Fire, and Water
