John Dalton - Solid Sphere Model
Based his model on the law of conservation of mass and the law of constant composition. -
J.J Thomson - Plum Pudding Model
The plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." -
Ernest Rutherford - The Nuclear Model
His gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. So from those results he proposed The Nuclear Model. -

Niels Bohr - The Bohr (Planetary) Model
In the planetary model the electrons revolved around a positively charged nucleus like the rings around Saturn—or alternatively, the planets around the sun. -
Erwin Schrodinger - Quantum Mechanics Model
In the quantum mechanical model of the atom, which treats electrons as matter waves. The electrons have an intrinsic property called spin, and an electron can have one of two possible spin values: spin-up or spin-down, and any two electrons occupying the same orbital must have opposite spins.
