Dalton: Solid Sphere Model
Did experiments with several chemicals and came to the conclusion that matter seemed to consist of lumpy particles. He didn't know much about it except that it was something fundamental. -
Thomson: The Plum Pudding Model
Thomson discovered the electron. He knew that they had a negative charge and made a model of the atom. -
Rutherford: The Nuclear Model
Rutherford did experiments and found out that there was a positive charge in an atom, which he later named proton. He knew that the electrons orbited the nucleus from a far distance. -
Bohr: The Bohr (Planetary) Model
Bohr said that electrons can orbit the nucleus but only from certain allowed distances. He also stated that only one electron can exist in an orbit. -
Schrodinger: Quantum Mechanics Model
Schrodinger used mathematical equations to estimate where an electron would be located. He assumed that matter could be both particles and waves.
