Which atomic model did Erwin Schrodinger create?
Schrodinger's wave equation was based on the Heisenberg uncertainty principal that the position and velocity of an electron cannot be defined accurately (accuracy in one will sacrifice accuracy in another). Schrodinger's wave equation gave a wave function, which squared gave the probability cloud of electrons. Thus, Schrodinger's contribution resulted in the electron cloud model of the atom.
