In the 1800's an English chemist, John Dalton performed experiments with various chemicals that showed that matter, indeed, seem to consist of lumpy particles (atoms). -
Plum Pudding Model
In 1897, J.J. Thomson discovered the electron and proposed a model for the structure of the atom. -
The Nuclear model
In 1911, Ernest Rutherford thought it would be cool to see inside of an atom. So he sort of probed an atom to try and look inside. -
The Bohr Model
In 1912, Niels Bohr came up with a theory that said the electrons do not spiral into the nucleus and came up with some rules for what does happen. -
Quantum Mechanics Model
In 1926, Erwin Schrödinger had an interesting idea: Why not go all the way with particle waves and try to form a model of the atom on that basis?
