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.
-
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.
-
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.
-
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.
-
Proposed by Erwin Schrodinger. He proposed the quantum mechanical model of the atom that treats electrons as matter waves.
