There have been multiple models and theories of the atom throughout history. The following list shows the main scientists involved, and what their big ideas were:
John Dalton: Indivisible atoms make up all matter.
J.J. Thomson: Electrons are scattered throughout a positively-charged sphere (the plum pudding model).
Ernest Rutherford: The atom has a positively-charged nucleus (the gold foil experiment).
Niels Bohr: Electrons orbit around the nucleus in energy levels.
Erwin Schrödinger: Electrons travel in clouds of probability called orbitals.
