Dalton: Solid Sphere Model
First atomic model, made by John Dalton. He hypothesized an atom was a solid mass that could not be separated into smaller parts -
Thomson: The Plum Pudding Model
Thomson described atoms as negative particles floating within a soup of diffuse positive charge. HIs model shows electrons as negatively charged particles embedded in a sea of positive charges. -
Rutherford's Nuclear Model
Rutherford saw the atom as a solar system, electrons orbiting a massive nucleus, with mostly empty space, while the nucleus is taking up very little space -
Bohr: The Bohr (Planetary) Model
The electrons encircle the nucleus of the atom in specifically allowed paths called orbits. -
Schrodinger's Quantum Mechanics Model
Schrodinger produced the quantum mechanics model which treats electrons as matter waves, they spin either up or down. Any electrons occupying the same orbital must have opposite spins. -
