Dalton
The Solid Sphere model- Dalton believed that the model of the atom was just a solid sphere. -
JJ Thomson
Plum Pudding Model- Electrons were added to the model. He discovered that negatively charged electrons that were balanced out with a positively charged "cloud" around them. Found using the Cathode Ray Experiment. -
Rutherford
Using the Gold Foil experiment, Rutherford found that an atom has a positively charged center (the nucleus). -
Bohr
Bohr created the atomic model where electrons orbit the nucleus. -
Heisenberg/Schrodinger
This is the modern atomic model. They added the uncertainty principle and wave mechanics to the model. -
Chadwick
Chadwick created a model that has neutrons in the nucleus.
