Dalton - Solid Sphere Model
Produced by John Dalton, who hypothesized that an atom was a solid sphere that couldn't be divided into small particles. It was the first atomic model. -
Thompson - The Plum Pudding Model
J.J. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup." This was one of several historic scientific models of the atom. -
Rutherford - The Nuclear Model
Proposed by Earnest Rutherford, which disproved J.J. Thomson's model of the atom as a uniformly distributed substance. Earnest Rutherford saw the atom as a miniature solar system with electrons orbiting around a massive nucleus. -
Bohr - The Bohr (Planetary) Model
Proposed by Niels Bohr and Ernest Rutherford as a system consisting of a small, dense nucleus surrounded by orbiting electrons. This is similar to the solar system. -
Schrodinger - Quantum Mechanics Model
Proposed by Erwin Schrodinger. He proposed the quantum mechanical model of the atom that treats electrons as matter waves.
