In 1906, Thomson created a current of negatively charged particles in a cathode-ray tube that were much smaller than an atom.

In 1908, Ernest Rutherford fired alpha particles (protons) at gold atoms and discovered that the center of the atom is densely packed and positively charged.

=4. __bohr's model__= In 1913, Neils Bohr introduced quantum mechanics into the atomic model.

5. Schrodinger's Model.



In 1926, Erwin Schrodinger introduced probabilty into the structure of the atom.
