Schrodinger (1925) Continued upon Bohr's findings to determine where electrons are typically found. Heisenberg (1927) Created the heisenberg uncertainty principle because you never can predict where the electron is. (Breaking Bad) De Broglie (1924) Electrons act like waves around the atom. Niels Bohr (Bohrbit) (1913) Electrons can orbit the nucleus in certain special orbits at different energy levels around the nucleus. Earnest Rutherford (foil) (1910) Fired beam of alpha particles at thin ...
