Dalton: Solid Sphere Model
Dalton thought atoms were solid and hard spheres. He modeled them with wooden balls -
Thomson: The Plum Pudding Model
Negative charged atoms were embedded with a positively charged area. Atom is mainly empty space with a positively charged nucleus. -
Rutherford: The Nuclear Model
Electrons were orbiting around a large nucleus in this model. Most was empty space and the nucleus occupied a small part relative to the rest of the atom -
Bohr: The Bohr (Planetary) Model date
negatively charged atoms orbit a nucleus in the middle the orbits were not planar -
Schrodinger: Quantum Mechanical Model
Each orbit has an energy associated with it. Electrons occupy only certain orbits around the nucleus.
