Dalton: Solid Sphere Model

Dalton was an English chemist and teacher who used experimental evidence to form the atomic theory of matter: -
Thompson: The Plum Pudding Model
http://www-outreach.phy.cam.ac.uk/camphy/nucleus/nucleus1_1.htm
An atom made of thousands of electrons would have a very high, negative electric charge. This was not observed, as atoms are usually uncharged. In 1906 Thomson suggested that atoms contained far fewer electrons, a number roughly equal to the atomic number. -
Rutherford: The Nuclear Model
http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/rutherford-model.html
The atom consisted of subatomic particles called protons and electrons. However, it was not clear how these protons and electrons were arranged within the atom. J.J. Thomson suggested the"plum pudding" model. In this model the electrons and protons are uniformly mixed throughout the atom. -
Bohr: The Bohr (Planetary) Model
http://csep10.phys.utk.edu/astr162/lect/light/bohr.html
The most important properties of atomic and molecular structure may be exemplified using a simplified picture of an atom that is called the Bohr Model. The correct theory of the atom is called quantum mechanics; the Bohr Model is an approximation to quantum mechanics that has the virtue of being much simpler. -
Schrodinger: Quantum Mechanics Model
http://www.abcte.org/files/previews/chemistry/s1_p6.html
This atomic model is known as the quantum mechanical model of the atom. Unlike the Bohr model, the quantum mechanical model does not define the exact path of an electron, but rather, predicts the odds of the location of the electron.
